When you get the error “modem not responding,” there are several steps you can take:

1. Check to see that the modem is connected and turned on.
2. Check the modem initialization string in the modem setup:
   1. Make sure that the init string is correct for your modem. Check your modem documentation for details.
   2. If there is a “^M” at the first of that string, remove it.
   3. Make sure that there is a carriage return or line feed character at the end of that string: “^M” in DOS or Windows, or “\r” in UNIX.
3. Try using a slower baud rate.
4. Ensure the modem is functioning by using HyperTerminal in Windows, cu in UNIX, or by typing echo ath1>comx (where “x” is the COM port that the modem resides on) at the command prompt in DOS.

There is also one known issue with TERM for UNIX, documented here.
