How To Load Cellular Drivers =============================== In order to be able to send data across your cellular phone, you must load the cellular driver for your phone into the modem's memory. Data interfaces between phone models vary, so it is important to load the correct driver. If a driver is not loaded, the modem cannot operate as a cellular modem. If a driver is loaded but the landline cable is attached, the modem will operate as a landline modem. The v34flash program has been provided on your Cellular Upgrade Kit Diskette to load the driver into flash memory. You will only have to load the driver once. (1) Insert the Data/Fax modem into the machine. (2) Insert the Cellular Upgrade Kit Diskette in your computer's diskette drive (3) At the DOS prompt or an OS/2 window, type a:(where a is the diskette drive that contains the Cellular Upgrade Kit Diskette) and press Enter. (4) At the prompt, type v34flash and press Enter. (5) Follow the displayed instructions. B. How to Bring up a Cellular Phone =================================== When bringing up the cellular phone, you can either be in DOS or in your communications software. It is recommended that you are in your communications software only if you can issue AT commands to check status or debug problems. (1) After the cellular driver has been loaded, get into DOS or your communications software. (2) Attach the cellular cable to your modem. (3) Attach the cellular phone to the cable. (4) Turn on the cellular phone. (5) Check the status before proceeding further by following one of the procedures under "Cellular Status and Troubleshooting". Your cellular phone is operational when you receive a result code of "176". C. General Cellular Phone Performance Tips ========================================== To improve cellular performance, issue the following AT initialization strings before utilizing a cellular phone. Locate your cellular phone make and model number from the following list and use its corresponding AT initialization string. Refer to your application software's documentation for further information on how to enter the initialization string. Phone (Make/Model #) AT Commands ------------------ -------------- Mitsubitshi 3500/4000, Diamondtel 20X/22X AT&F1-SEC=1,17 Motorola 8 pin flip AT&F1-SEC=1,10 NEC P110/P120/TalkTime 180, AT&T 3610 AT&F1-SEC=1,14 NEC P700/P701 AT&F1-SEC=1,16 OKI 1145/1150, AT&T 3760 AT&F1-SEC=1,10 Nokia 2120, AT&T 6650 AT&F1-SEC=1,10 OKI 1300 series (1325/1335/1375) AT&F1-SEC=1,10 Use the MNP10EC command, -SEC=n, exclusively over the MNP10 commands (*Hn, -Kn, )Mn, @Mn, -Qn, :En). Otherwise you will be mixing protocols and will not receive the full performance advantages of MNP10EC. It is recommended that the remote modem also be MNP10EC compatible for the most reliable data communications. If the remote landline modem is MNP10EC compatible, then the remote landline end should enable MNP10EC by setting the -sec=n command as follows: at-sec=1. After you issue the AT commands, the Data/Fax modem is ready for cellular use. Certain cellular phone and computer conditions affect cellular performance. Ensure that the following conditions are maintained: (1) Ensure that the cellular phone battery is at least 3/4 charged. (2) Ensure that the cellular phone signal is strong. The cellular phone signal should be only 1 or 2 signal strengths below the maximum signal strength. Refer to your Cellular phone manual for further information on signal strength. (3) Try not to move the cellular phone during cellular use. Moving the cellular phone results in low phone signal strength. (4) Close applications on your computer other than the cellular phone application during cellular phone use. D. Data Communication Tips =========================== Follow these tips to improve data communications: (1) Use a protocol that has a high degree of error control, such as ZMODEM, to send or receive files. This type of protocol should be on both the local and remote modem. If you send or receive a file with ZMODEM, and the transfer does not complete, reestablish the connection. Send or receive the file again without deleting the partially received file. ZMODEM will pick up where it left off and attempt to transfer the remainder of the file. (2) If data send or receive problems are encountered, lower the maximum data connection rate using the +MS command. (3) MNP10EC and MNP10 protocols handle adverse line conditions such as those encountered in cellular communication. If the landline modem does not use one of these two protocols, you may have trouble transferring files between the cellular and landline modems. In this situation, the use of a modem pool may allow you to do file transfers. A modem pool puts a modem between the cellular modem and the landline modem. The modem pool should have at least MNP10-compatible modems to be useful. Contact your cellular carrier to see if they offer modem pools and to learn how to access them. E. Fax Communication Tips ========================== If Fax send or receive problems are encountered, lower the Fax maximum send and receive speeds in your Fax application. F. Online Services =================== If you are experiencing problems connecting to online services (for example, America Online, Prodigy, BBS), try reducing the modem speed or try a different access number. G. Cellular Status and Troubleshooting ====================================== After you load the driver, you may have problems powering up certain phones once they are attached to the cellular cable and modem. Either bring up your communications software or run v34cell described in this section so that the phone will power up. If you are experiencing problems using the cellular phone or wish to check status, use one of the following procedures to verify the cellular phone is set up correctly. (1) If you are using the communication software application that allows you to issue AT commands: (a) Start up the communication software application. (b) Type the following AT commands: AT Command Description ---------- --------- at^i Displays cellular driver loaded on the modem. at^t6 Displays status of cellular phone cable. The most common result codes and their meanings are as follows. See the online documentation for more information: 000 The cellular cable is not detected. Try reattaching the cellular cable to the modem. 160 The cellular cable is detected but the cellular phone is not detected. Try reattaching the cellular cable to the cellular phone. Verify that the cellular phone is powered on. 184 There is no cellular phone service. 176 The cellular phone is operational. Note that cellular phone designs and specifications differ between manufacturers and models. Therefore it cannot be guaranteed that a particular phone produces the conditions necessary to generate a given result code for the at^t6 command. (2) If you are unable to issue AT commands other than an initialization string with your communication software application, or you would simply like to use the v34cell utility, do the following: (a) Insert the Data/Fax modem into the machine. (b) Insert the Cellular Upgrade Kit diskette in your computer's diskette drive. (c) At the DOS prompt or an OS/2 window, type a:(Where a is the diskette drive that contains the Cellular Upgrade Kit Diskette) and press Enter. (d) At the prompt, type v34cell and press Enter. (e) Follow the displayed instructions. You will be able to: (a) Verify that the correct cellular driver is loaded. (b) Verify that the correct level of microcode is loaded. (c) Determine the status of the cellular phone cable. (See the result codes previously defined for at^t6.) If you switch from a cellular connection to a landline connection without powering off the computer or reinserting the PC card, you can receive an error when issuing AT commands. Power off the computer or reinsert the PC card to reset the modem and avoid the error. -------------------------------------------------------------------------------- Section 2: Converting PCMCIA 28.8/14.4 Data/Fax Modem to the PCMCIA 33.6/14.4 Data/Fax Modem DO THE FOLLOWING: 1) IN DOS OR OS/2 OR WINDOWS95, OPEN UP A WINDOW. 2) INSERT THE DATA/FAX MODEM CARD (In Windows 3.1, you have to insert the modem and THEN START WINDOWS for Windows 3.1 to Recognize the card, this goes for ANY Card) 3) PUT THE PCMCIA 33.6/14.4 DATA/FAX MODEM DISKETTE INTO THE A: DRIVE. 3) TYPE A: (AND ENTER) 4) TYPE V34FLASH 5) THE FIRMWARE WILL BE CHANGED AND YOU WILL GET A SUCCESSFUL COMPLETION MESSAGE SAYING SO. 6) YOUR MODEM NOW HAS THE CAPABILITY OF OPERATING AT UP TO 33.6 Kbps.
