C:The telephone switch may have disconnected your call.
C:Your software may have turned off the DTR signal.
Q:The modem does not connect with another modem.
C:There may be a problem with the remote modem if you do not hear the high
pitched tone from the remote modem.
Q:Occasionally, the modem gives a burst of errors.
C:The telephone line may be noisy or bad.
A:Hang up the call and try to connect again for getting a better telephone line.
C:If there are other telephones on the same line that your modem is using,
someone may have picked up a telephone on that extension.
C:Your telephone line may have the call waiting feature.
A:Try adding '*70,' to your ATDT dialing command line. If it doesn help, ask
your telephone company how to disable it temporarily.
Q:The modem gets errors in transmitted data randomly.
A:Try to use V.42 or MNP1-4 if possible.
A:Connect the modems at a slower baud rate.
Q:After you download a file, it was not stored on your disk drive.
C:If both modems are using MNP or V.42 protocol, then the flow control may
not be enabled.
A:Configure your software to use RTS/CTS flow control. That will cause your
computer to pause long enough for the file to be stored to disk.
Q:The text on the screen is not legible.
C:Your software settings may not match the settings on the remote site.
A:Make sure your data bits, stop bits, and parity settings match the settings that
the other computer is using. The two most common settings are: 8 data bits,
None parity, and 1 stop bit (8,N,1) or 7 data bits, Even parity, and 1 stop bit
(7,E,1).
C:If the telephone line is very noisy, you may see corrupted data on your
screen.
C:Due to poor telephone line conditions, the modem may have fallen back to a
slower communication speed. You may need to change the baud rate setting in
your software to match this slower speed. To return the modem to the higher
speed, disconnect the link and re-establish again.
Q:When using V.42bis or MNP5, some features are disabled.
C:You may be using a non-streaming protocol, like Xmodem or Ymodem to
transfer files. Those are fine unless you are using V.42bis or MNP5
A:When using V.42bis or MNP5, you should use a streaming transfer protocol
like Ymodem-G or Zmodem.
A:Configure your software to use hardware flow control (RTS/CTS ON).
Q:When the modem is connecting to another modem, it reports a higher
connect baud rate that it is really using.
C:The modem defaults to report the modem-to-computer baud rate when it
responds with CONNECT.
A:Go to command mode with your communication program (like Telix) and type
ATW2, then press Enter. This tells the modem to report the modem-to-modem
baud rate instead
