INTRODUCTION ================================================================= This document aims at providing solutions for the most common problems that you might encounter while using the PC Suite for Nokia 8250. ================================================================= 2. ABBREVIATIONS USED IN THIS DOCUMENT ================================================================= bps Bits per second FIFO First In First Out SIM Subscriber Identification Module TAPI Telephone Application Programming Interface UART Universal Asynchronous Receiver/Transmitter IrDA Infrared Data Association ================================================================= 3. PROBLEMS AND EXPLANATIONS ================================================================= 3.1 "PC SUITE FOR NOKIA 8250 DOES NOT RESPOND ANYMORE" You should activate your phone infrared transfer again and restart PC Suite for Nokia 8250. ----------------------------------------------------------------- 3.2 "DURING A DATA CALL PC SUITE FOR NOKIA 8250 DOES NOT RESPOND" It is not possible to use the PC Suite for Nokia 8250 user interface during a data call. End your data call and restart the PC Suite for Nokia 8250. ----------------------------------------------------------------- 3.3 "I WOULD LIKE TO USE A 16-BIT COMMUNICATION APPLICATION WITH NOKIA 8250, BUT I DO NOT KNOW HOW TO CONFIGURE THE COMMUNICATION APPLICATION." 16-bit applications do not support Unimodem/TAPI, so you have to manually specify the communication port which Nokia 8250 is using. Example: If the Infrared Monitor displays application support on COM4, you should specify COM4 as modem port in your communication application. ----------------------------------------------------------------- 3.4 "I HAVE USED MICROSOFT EXCEL TO EDIT ONE OF MY CONTACTS DIRECTORY FILES (*.CSV), BUT SOME OF THE TELEPHONE NUMBERS WERE DISPLAYED IN SCIENTIFIC NOTATION." The remedy for this is to set the format of all the cells of the column containing the telephone numbers to "Number" with no decimal places. You can achieve this by first selecting the relevant column, pressing CTRL-1, selecting "Number" and finally setting the number of decimal places to 0. ----------------------------------------------------------------- 3.5 "I WOULD LIKE TO SAVE A CONTACTS DIRECTORY FILE THAT I HAVE EDITED IN MICROSOFT EXCEL, BUT I AM NOT SURE WHICH FILE TYPE TO SPECIFY FOR SAVING." To ensure that your contacts directory file will be saved in a format that can be read by PC Suite for Nokia 8250, save it as type "CSV (Comma delimited)". ----------------------------------------------------------------- 3.6 "I HAVE CONFIGURED MY DATA APPLICATION TO USE 7 DATA BITS INSTEAD OF 8, BUT NOW I HAVE TROUBLE ESTABLISHING A CONNECTION." Certain cellular networks do not support 7-bit data calls and connection problems may occur if applications have been configured for 7-bit use. Before configuring any application to use 7-bit data, make sure that your network supports this. If the network does not support it, and if you have problems, you may have to re-configure the application to use 8-bit data (8N1) instead. ----------------------------------------------------------------- 3.7 "I WOULD LIKE TO USE DATA TRANSFER SPEEDS OTHER THAN 9600 BPS, BUT WHENEVER I SPECIFY THIS IN MY DATA APPLICATION, I EXPERIENCE CONNECTION PROBLEMS." Configuring data applications to use transfer speeds other than 9600 bps (default) may cause data transfer or connection problems, if not supported by your SIM. Therefore, before changing the default data transfer speed, make sure that your SIM has been configured by your network operator to support speeds other than 9600 bps. If other data transfer speeds are not supported, you should always use a data transfer speed of 9600 bps. ----------------------------------------------------------------- 3.8 "I EXPERIENCE VERY BAD DATA THROUGHPUT SPEEDS." Make sure that the serial port to which your phone is connected uses FIFO buffering. You can enable this within the serial port settings, but only if your communication port is equipped with a 16550 or compatible UART. ----------------------------------------------------------------- 3.9 "WHENEVER I DIAL A NUMBER, THE WRONG AREA AND COUNTRY CODES ARE DIALLED." Make sure that these have been set up correctly in the modem's dialling properties. You can inspect and change these in SETTINGS->CONTROL PANEL->MODEMS->Dialling Properties. Ensure, however, that the settings are displayed/changed for the correct modem (Nokia 8250) if you happen to have other modems installed as well. ----------------------------------------------------------------- 3.10 "I INTEND TO USE BOTH NOKIA CELLULARWARE AND Nokia 8250 ON MY COMPUTER, BUT I AM NOT SURE WHETHER THAT IS POSSIBLE." If you intend to use both Nokia CellularWare and Nokia 8250, ensure that these applications do not use the same physical communication port. ----------------------------------------------------------------- 3.11 "WIN95 INFORMED ME ABOUT ANOTHER PROGRAM USING MY MODEM, BUT I DID NOT HAVE ANY OTHER PROGRAM LOADED." If Win95 claims that "Another program is using the modem, close the other program...." and no other program is actually using the modem, then reboot the computer to recover from this situation. Also when setting up a remote connection with MS Exchange, it might occasionally complain about the modem-port being already in use, without establishing any connections. If this happens, re-start MS Exchange. ================================================================= 4. IrDA CONNECTIONS ================================================================= 4.1 "HOW CAN I CHECK THE IrDA CONNECTION " Before using PC Suite for Nokia 8250 via IrDA, you can test the IrDA port functionality in a following way : * Open the Microsoft Infrared Monitor * Check that Infrared communication is enabled in your system * Check that the Nokia 8250 is found with the Infrared Monitor (follow the instructions for activating the infrared connection in your Nokia 8250's User Guide) ----------------------------------------------------------------- 4.2 "MULTIPLE NOKIA 8250 MODEMS INSTALLED" It may be advisable not to select "Enable software install for Plug and Play devices in range" from Infrared Monitor as it interferes with the installation of the PC Suite for Nokia 8250. ================================================================= 5.
