`ABSTRACT
`
`An option attach connector has a first indicator bit combi-
`nation that alerts the device that a public switched telephone
`network connection has been made to it. The presence of the
`first indicator bit combination is a signal to the device that
`telephone, FAX, and E—MAIL communications applications
`are to be conducted over a PSTN link. The presence of the
`first indicator bit combination invokes a stored computer
`program to provide appropriate connections between the
`PSTN link and the telephone, FAX, and modem hardware in
`the device. The connections are made by an audio multi-
`plexer that receives control signals from the system CPU,
`while executing the stored computer program. The program
`determines the communications application selected by the
`user and selectively configures the PSTN link to be con-
`nected to the either the ear piece and microphone for voice
`communications, or to the FAX/modem for FAX commu-
`nications, or to the modem alone for E-MAIL communica-
`tions. The absence of the option attach connector invokes a
`default indicator bit combination that alerts the device that
`
`a cellular telephone network connection is desired by the
`user. The presence of the default indicator bit combination is
`a signal
`to the device that telephone, FAX, and E-mail
`communications applications are to be conducted over a
`cellular network.

`
`BACKGROUND OF THE INVENTION
`
`It is widely recognized that digital communications tech-
`nology and data processing technology are converging. One
`example of this is the development of portable personal
`computers that include telephone modems, enabling the
`transmission of digital information over public switched
`telephone networks (PSTN). Another example is the devel-
`opment of mobile radio telephones that use microprocessors
`executing stored programs for sampling and digitizing the
`voice signal, multiplexing the transmission of the digitized
`voice signal with other such voice signals, and digitally
`controlling the operations of the cellular telephone device.
`The most recent evidence of the convergence of digital
`communications technology with digital personal computer
`technology, is the SIMON personal communications device
`
`2
`
`described in the above identified patent applications. The
`SIMON personal communications device has many features
`within it to enable personal communications. The personal
`communications device provides a cellular telephone, a
`facsimile transmission and receiving capability, an elec-
`tronic mail sending and receiving capability, and an elec-
`tronic pager, a computer notepad, a computer address book,
`a computer calendar, and a computer calculator, all within a
`single compact portable package.
`The SIMON personal communications device includes a
`central processing unit (CPU) that executes stored pro-
`grammed instructions stored in electrically programmable
`read only memories (EPROM). The stored program instruc-
`tion in the EPROM’s include basic input output operating
`system (BIOS) programs, and application programs to per-
`form the functions of cellular telephony, public switched
`telephone network (PSTN) telephony, facsimile transmis-
`sion and reception, electronic mail, pager functions, com-
`puter notepad functions, computer address book functions,
`computer calendar functions, and computer calculator func-
`tions. These stored programs are selectively accessed for
`execution by the CPU.
`The SIMON personal communications device also
`includes a liquid crystal display having a touch overlay
`membrane, to enable the user to input keyboard entries or
`sketches by tactile pressure with a finger or proximity with
`a stylus. One example of a touch overlay membrane input
`device is described in U.S. Pat. No. 4,686,332 by Evon
`Greanias, et al., entitled “Combined Finger Touch and Stylus
`Detection System for Use on the Viewing Surface of a Visual
`Display Device”, assigned to the IBM Corporation and
`incorporated herein by reference.
`The storage capacity of the RAM can be augmented by
`employing supplementary memory in the form of a personal
`computer memory card (PCMCIA) (Trademark of the Per-
`sonal Computer Memory Card International Association).
`The personal computer memory card can include extra RAM
`to supplement the RAM storage in the personal communi-
`cations device, by plugging the personal computer memory
`card into a PCMCIA receptacle slot in the personal com-
`munications device.
`
`The LCD screen presents menu images to the user to
`enable the selection of communications applications such as
`telephone, facsimile (FAX), or electronic mail (E-mail). For
`each of these applications, a corresponding keypad and
`presentation area is displayed. The user has the option of
`employing either a public switched telephone network link
`or a cellular telephone network link for any of these com-
`munications applications. However, the functions required
`to be performed in order to send or receive a cellular
`telephone network call are diiferent from the functions
`required for a call over a public switched telephone network.
`All cellular telephones use two-way radio communica-
`tions controlled by the cellular telephone network. The
`ambient atmospheric and geographic conditions can affect
`the strength of the transmitted signal. When transmitting a
`large amount of data during a FAX or an E-mail session, an
`acceptable signal strength is required to ensurethat data is
`not lost and to keep the transmission error-free. A signal
`strength indicator is required on cellular telephones to
`enable the user to monitor the signal strength and change its
`location to improve it. Further, a cellular telephone must be
`registered with the home region it usually employs as the
`base for its communications. If the cellular telephone is
`transported outside of its home region, it becomes a roarner,
`and a dilferent mode of operation called roaming, is carried

`
`out. A cellular telephone must provide an indication to the
`user as to its current mode of operation, either home or
`roaming. Such concerns are absent from calls using a public
`switched telephone network.
`The personal communications device requires the ability
`to selectively reconfigure itself, based on the input and
`output connections attached to it by the user and based on
`the communications applications selected by the user.
`
`OBIECTS OF THE INVENTION
`
`is therefore an object of the invention to provide
`It
`selective reconfiguration for a multiple application personal
`communications device.
`
`It is another object of the invention to provide selective
`reconfiguration for a multiple application personal commu-
`nications device, that adapts to the unique requirements of
`the selected communications link.
`
`It is a further object of the invention to provide selective
`reconfiguration for a multiple application personal commu-
`nications device for communication over both public
`switched telephone networks and cellular telephone net-
`works.
`
`SUMMARY OF THE INVENTION
`
`These and other objects, features and advantages are
`accomplished by the method and apparatus for consistent
`user interface disclosed herein.
`
`The invention is used in a personal communications
`device that includes a memory that stores the operating
`system programs and the applications programs for execu-
`tion by a central processing unit (CPU) in the device. The
`programs selectively manage the operations of a cellular
`telephone, a facsimile receiver, a touch overlay input and
`display, and several desktop functions such as a calendar,
`notepad, and electronic mail.
`The device is capable of performing many types of
`communications functions that require a variety of commu-
`nications links. In addition to the radio link provided for
`cellular telephony, the device must be able to connect to a
`conventional RJll telephone jack for public switched tele-
`phone service, to an RS232 serial data connector, to diag-
`nostic cables,
`to external keyboards, and to hands-free
`microphones and speakers. To consolidate these connection
`requirements, an option attach connector is provided for the
`device. The option attach connector includes three program-
`mable indicator bits that indicate to the device, the role the
`connector is playing when it is connected to the device.
`In accordance with the invention, the option attach con-
`nector has a first indicator bit combination that alerts the
`device that a public switched telephone network connection
`has been made to it. The presence of the first indicator bit
`combination is a signal to the device that telephone, FAX,
`and E-MAIL communications applications are to be con-
`ducted over a PSTN link. The presence of the first indicator
`bit combination invokes a stored computer program to
`provide appropriate connections between the PSTN link and
`the telephone, FAX, and modern hardware in the device. The
`connections are made by an audio multiplexer that receives
`control signals from the system CPU, while executing the
`stored computer program. The program determines the com-
`munications application selected by the user and selectively
`configures the PSTN link to be connected to the either the
`ear piece and microphone for voice communications, or to
`
`4
`the FAX/modem for FAX communications, or to the modem
`alone for E-MAIL communications.
`
`Further, in accordance with the invention, the absence of
`the option attach connector invokes a default indicator bit
`combination that alerts the device that a cellular telephone
`network connection is desired by the user. The presence of
`the default indicator bit combination is a signal to the device
`that telephone, FAX, and E—mail communications applica-
`tions are to be conducted over a cellular telephone network.
`The presence of the default
`indicator bit combination
`invokes the stored computer program to provide appropriate
`connections between the cellular telephone interface and the
`telephone, FAX, and modern hardware in the device. The
`connections are made by the audio multiplexer that receives
`control signals from the system CPU, while executing the
`stored computer program. The program determines the com-
`munications application selected by the user and selectively
`configures the cellular telephone interface to be connected to
`the either the ear piece and microphone for voice commu-
`nications, or to the FAX/modem for FAX communications,
`or to the modem alone for E-MAIL communications.
`
`In this manner, selective reconfiguration is provided for a
`multiple application personal communications device, that
`adapts to the unique requirements of the selected commu-
`nications link and to the selected communications applica-
`tion.

`
`DISCUSSION OF THE PREFERRED
`EMBODIMENT
`
`The personal communication system diagram of FIG. 1A
`shows the personal communications device 100. The device
`100 includes the RAM 102 which is connected by means of
`the bus 104 to the CPU 106, which executes the stored
`program instructions in the RAM 102. RAM 102 contains
`the ink plane bufi°er 164 used by the touch overlay mem-
`brane to store pels of registered contact points by the user’s
`finger of stylus. RAM 102 contains the display buffer for the
`LCD display 112. Screen images, such as image SOA in FIG.
`1A and FIG. SA, are represented by a bit map stored in the
`display buffer 162, that displays the bit map as the image
`50A, for example on the display 112. The work space 138 in
`RAM 102 is used by the operating system program 150 and
`BIOS 134, as well as by application programs running in the
`device 100.
`
`Register 136 stores the option value that is decoded by the
`decoder 122 from the resistor array 220 in the option attach
`connector 126(0). The interface program 180, stored in
`RAM 102, reads the option value stored in register 136 and
`in response, sends control signals to the audio MUX to
`configure the connections 60A, for example, between the
`option attach connector 126(0) and the ear piece and micro-
`phone 117. This is described in the flow diagram of FIGS.
`4A to 4D.
`
`The interface program 180 also controls the display of
`images such as 50A on the display 112, in response to
`reading the option value stored in the register 136. This is
`described in the flow diagram of FIGS. 4A to 4D. FIG. 6
`illustrates the layout of the master image SOX produced by
`the interface program 180. When the interface program
`generates the PSTN telephone function image 50A, for
`example, it accesses the PSTN screen file 182 in RAM 102
`which contains the layout of the PSTN customizing image
`SOY shown in FIG. 6A. The interface program 180 combines
`
`6
`the PSTN customizing image SOY with the master image
`50X of FIG. 6, to produce the composite image 50A of FIG.
`1A and FIG. SA, as it is displayed on the display/touch
`overlay 112, for voice communications over a PSTN.
`The RAM 102 also stores the cellular screen file 184, that
`contains the layout of the cellular customizing image S02,
`that when combined with the ma
