Information on other programs is available in other documents. See the catalog for a complete list of documents. GENERAL TROUBLESHOOTING 1. Make sure the phone line is plugged in. 2. Use Alt-P to check whether the correct COM port and baud rate are selected. 3. Check the modem for response by typing AT in the terminal mode. The modem should respond with OK. 4. Run TESTCOM. 5. If these steps don't help you, contact Magicsoft at (312) 953-2374. DOESN'T HANG UP PHONE MTE uses DTR to hang up the phone. Intel's non-MNP modems (2400B Classic, 2400EX, and CCP Modem Option) are factory set to ignore DTR (&D0). When MTE toggles DTR to hang up the phone, the modem doesn't respond. Make sure the setup string contains the command &D2. Intel MNP modems (2400B Classic MNP, 2400EX MNP, and 9600EX) are factory set to use DTR (&D2). See the Command Guide for more information on modem configuration commands. CAN'T ESTABLISH CONNECTION If you can't establish a connection with MTE, disable the MNP. Some systems can't tolerate the extra hand-shaking necessary for an MNP connection. CARRIER ALREADY ESTABLISHED MESSAGE If you receive this message before the modem dials the phone number, change the value of DCD. The default setting for Intel modems is DCD set to 0 (&C0); this is the Hayes standard. However, many software packages require &C1 to work. Use this command to set DCD: AT&C1.

If you believe the MNP is not working, and the ALT-S setup screen shows that it's enabled, contact MagicSoft at (312) 953-2374. FILE TRANSFERS USING MTE When transfering files an MNP connection, use either Ymodem-G (included) or Zmodem (optional) protocol. These protocols don't perform error correction (MNP does its own error correction). For non-MNP connections, use Xmodem or Ymodem. CONNECTS AT MNP 2 OR 4 WHEN MNP 5 IS SELECTED This occurs either when the modem on the other end is an MNP 2, 3, or 4 modem OR when the operator has turned off level 5. This is common on BBS's because most files are already compressed. The MNP 5 compression can actually slow the the transfer of compressed files. MODEM DOESN'T DIAL If you're on an in-house phone system, check with your system administrator to see if the phone system supports modems. You may need a dedicated modem line. Your communications program may need the DCD or CARRIER signals to reflect the modem's status rather then being ON all the time (the default setting). Use the command AT&C1&W to ensure the modem is set to work with these programs. This can also be caused by an incorrect data format set up. If you select a "word length" of 7, you must set "parity" to something other than "no parity" (ie. even, odd, mark, space, ect...). Be sure the data format you use matches that of the computer you're calling. MODEM WAITS A LONG TIME BEFORE REDIALING MTE doesn't respond to modem response codes regarding a busy signal. Instead, it waits for the modem to time-out before redialing. You specify the time-out period in the modem's S7 register. If this value is set to 30 seconds, MTE's response should appear reasonable. If this value is set near the maximum (255), MTE will wait a long time before redialing.

This is due to the added overhead of MNP error correction. If you can make the connection reliably without MNP, you can improve MTE's performance by disabling MNP before making the call. NOTE: You can NOT toggle MNP off and on during a call. Once a connection has been established, the mode remains unchanged until the connection is terminated. For an interactive link, screen updates will be slower with an MNP 4 connection, but an MNP 5 connection should be faster than a non-MNP connection because of the data compression. PARAMETERS/PROTOCOLS FOR REMOTE LINKS You can customize the parameters and protocols MTE uses to match the needs of the remote systems. The most common settings (the ones the Intel BBS uses) are 8,1,N (8 data bits, 1 stop bit, no parity). The most common file download protocol on non-MNP services is probably Xmodem. You set the parameters in MTE by pressing ALT-P. You choose the download protocol when the download is initiated. RECOMMENDED SETUP STRING The recommended setup string for MTE is AT&F&S1&C1&D2&W. You can check the setup string by pressing Alt+S. XMODEM/YMODEM DOESN'T WORK WITH MNP LEVEL 5 When using MNP, use a protocol written specifically for MNP connections (such as YModem-G and Zmodem). If you don't, the protocol will provide error correction in addition to the MNP error correction and you'll lose performance.
