DATA COMMUNICATION OPERATION  
The Fax/Data Modem may be used to connect to an On-Line service, local BBS (Bulletin Board System) or the Internet. This connection may require different communication parameters. The  
following parameters are the basic settings needed for a successful connection:  
1. Data Bit  
8 Data bit is the most common setting.  
7 Data bit some for On-Line service and mostly Main frame connection.  
2. Stop Bit  
3. Parity  
1 Stop bit is widely use.  
There are three setting: ODD, EVEN or NONE depends on the system you are trying to connect.  
The speed that the data traveling between the modem and your computer. The setting should be four times of your modem speed. For example:  
4. Baud Rate  
Modem Speed  
2400 bps  
Baud Rate selection

9600 bps  
38,400 bps  
57,600 bps  
115,200 bps  
14,400 bps  
28,800 bps  
5. Flow Control  
Set the flow control between the computer and the modem can prevent data over run during transmission. There are two common ways of setting the flow control.  
Software Flow control or XON/XOFF  
Hardware Flow Control or CTS/RTS  
Most of the data communication software has the option for setting the above parameters. In order to let the modem communicate flawlessly, these settings must be identical between the two modems except  
Baud Rate and Flow Control.

OPERATING MODE  
OPERATING MODE  
OPERATING MODE  
The Fax/Data Modem operating modes, which is selectable by the \Nn command, these commands allow the DCE (modem) to communicate with remote modems that may or may not support error  
correction and data compression. The operating modes are Normal, Direct, Reliable link, Auto-reliable, V.42 Reliable Mode, and MNP Reliable Mode. Speed buffering, which is used for all operating modes  
except \N1, allows the DTE(computer)-to-modem data rate to be different from the modem-to-modem data rate. This is accomplished by using transmitting and receiving buffers in the modem as speed buffer.  
Thus, the DTE-to-modem data rate can be set for 38,400 bps when the modem-to-modem data rate is 9,600 bps, without causing any data errors. In all data modes except direct mode (\N1), the DTE-to-  
modem data rate can be set for any valid speed between 300 bps and 57,600 bps. (In direct mode, the DTE-to-modem data rate can only be set to 300, 1200, 2400, 4800, 7200, 9600, 12000, and 14400  
bps.)  
Each operating mode is explained as the following:  
Normal Mode  
%
No error correction/data compression, but speed  
buffering is supported.  
Direct Mode

File Transferring  
To transfer files between two computers user will need to choose a file transfer protocol once the two modems are connected. There are many different types of file transfer protocol. Each has  
advantage and disadvantage on their own. The following are some guide - line in file transferring:  
C
C
After log in to a remote computer check, the protocol its using. Make sure your protocol matches the remote computers. Here are, some names of the popular protocols: COMPUSERVE B,  
Kermit, XMODEM, YMODEM, ZMODEM.  
The remote computer will wait for a user to start the file transfer sequence. The user must tell the communication software to start sending or receiving the selected files.  
Remote Access  
The best source of the information for setting up a remote access software is its User=s manual. A user needs to fill in which type of modem to use (consult the modem choice section) and the flow  
control selection.  
If you are having some difficulty connecting to a remote computer, change the init string for the modem to use Normal or Direct Mode. Some of the remote access programs have an error correction  
and/or data compression built-in to the software. Disabling Fax/Data Modem=s errorcorrection and/or data compression may be required for this operation.  
CELLULAR OPERATION  
For the >Cellular ready= modem owner, you will need to obtain a proper cellular interface cable kit that matches the make and model your cellular phone.(see the Notice: below)  
Please follow these suggestions:  
C
C
C
Verify if the modem is installed and recoqnized by the system. Using PCMCIA sockets driver utility such as Cardinfo or PCMWIN etc.  
Check the modem operation with the land line using any communication program for DOS or Windows.  
You need to run an installation program to activate the cellular function included with the cellular interface kit. For more details consult the User=s manual and the README file in the driver  
diskette.  
For the >None - Cellular ready= Fax/Data Modem, you will need a cellular interface adapter. This adapter provide Dial Tone for the modem and cellular cable kit matching your cellular phone make and model.

DIAGNOSTIC  
DIAGNOSTIC FUNCTION  
Setting up for the diagnostic operation: Start the data communication software, then enter the >Terminal Mode= or >Connect Mode=. Set the COM port to match the number use by the modem type >at= then press  
ENTER key to check the modem installation.  
The Fax/Data Modem supports diagnostic functions defined by ITU (CCITT) V.54 to assist identifying problems of the modem. Basically, these functions loop signals on the local and remote modems to  
simulate data communication activities.  
These diagnostic functions must be performed under asynchronous operation in non-error-correction mode(normal or direct mode). In command mode, use AT\N1 to enter direct asynchronous mode. To stop  
any diagnostic functions in progress, use the escape (+++) sequence to go to command mode, and type AT&T0 .  
Local Analog Loopback  
This test will loop data from computer to the modem. Use AT&T1 to start the test. CONNECT XXXXX message will be displayed upon the start of the test. After the connection, characters typed on  
the computer will be transmitted to the modem and then return to the computer to be displayed on the screen.  
Local Analog Loopback with Self-test  
Use AT&T8 to initialize this test. The modem will generate a test pattern and looped back and checked by the modem itself. The testing duration is set by the contents of S18. Upon the termination  
of the test, it returns the number of detected errors to the computer. Register S16 bit 6 will be set when the test is in progress.  
Remote Digital Loopback  
Use AT&T6 to initialize this test. The test is to check the connection fault between a local modem and a remote modem. Data is routed from local computer to the local modem, then through the  
phone connection to a remote modem. The remote modem then retransmit the data through the same connection back to the local modem, then to the local computer. Before the test, you must establish a  
connection with a remote modem. If no connection is made, ERROR message will be returned. The CONNECT XXXX message will be displayed upon the start of the test. After the connection, all characters  
you typed on computer will be remote loopbacked and redisplayed on your screen.  
Remote Digital Loopback with Self-test  
Use AT&T7 to initiate the test, and a test pattern will be looped back and checked by the modem. If no connection is made before the start of the test, ERROR message will be returned. The test  
duration is determined by the contents of S18. Upon the termination of the test, it returns the number of detected errors to the computer. Register S16 bit 5 will be set when the test is in progress.  
Local Digital Loopback  
Before the start of the test, a connection to a remote modem must be established. If no connection, ERROR message will be displayed. Use AT&T3 to start the test. After the start of the test,  
characters typed on the remote computer will be routed from the remote modem to the local modem through the connection. The local modem will then return the data to the remote modem, and then  
redisplayed on the screen of the remote computer. Register S16 bit 4 will be set when the test is in progress.

APPENDIX A  
What is PC Card (PCMCIA) device driver?  
A PC Card device driver contains several components: Socket services, Card services, Resource Initialization Utility and Card Installation Utility. The remaining of this section will explain the four components  
and list the names of the device driver for some major PC Card software vendors.  
Socket Services provides the interface between a system*s BIOS and the host controller chips (such as the Intel 82365SL PCIC and the DataBook TCIC-2/N). Socket Services includes functions such as  
configuring a socket for an I/O or memory interface and controlling socket power voltages. The Socket Services driver operates the host controller chip of your computer.  
Card Services provides the interface between the PC Card card and the Sockets Service driver. To make sure Card Services operate flawlessly regardless of the system, some PC Card device driver provide  
their own resource initialization utility, which will check all of the I/O ports, IRQs, and memory addresses used by the computer and report that information to Card Services.  
The Card Installation Utility detects the insertion and removal of a PC Card, and determines the card type upon insertion, then the card and socket will be configured properly.  
These components are loaded into the system during boot-up via the statements in the C:\CONFIG.SYS file. Along with the four components you may find other types of device drivers for various types of PC  
Card like SRAM card, FLASH memory card, and ATA/IDE hard drive card.

APPENDIX B  
APPENDIX B  
S REGISTERS  
The S registers are summarized in table along with their default values. Registers denoted with an '*' in the table may be stored in one of the two user profiles by entering the &Wn command. One of these  
profiles may be loaded at any time by using the Zn command. Registers or register fields quoted as "reserved" are reserved for current or future use by the firmware, or are permanently overridden by PTT  
limitations.  
All bit-mapped registers are read-only. The appropriate AT command which controls the relevant bits in the S-register should be used to change the value.  
FACTORY DEFAULTS  
The factory default values are stored in ROM and are loaded into the active configuration at power up or by the AT&F command. In addition, the designated default profile is subsequently loaded, and may  
change some of the factory default values. The designated default profile can be changed by entering the &Yn command where n is one of the two possible user profiles.  
The defaults shown are those used in factory profile. All of the factory default values may be loaded at any time by entering the &F command.
