This sounds like you have a cabling or modem  problem.   Here  is
the  pinouts for a modem cable that I use for all different kinds
of modems and models of Towers.


                DB15             DB25
		  1 -------------  2
                  2 -------------  4
              |-- 3 -------------  6
              |   4 ------------- 20
              |   .                .
              |   9 -------------  3
              |  10 -------------  5
              |  11 -------------  7
              |--12 -------------  8

If you need a DB9 instead of a DB15 just replace the numbers 9-12 with
6-9 respectively.

Secondly, what kind of modem do you have?  Many modems have reset
options  built  in  that  can send out the equivalent of ATZ upon
termination of the connection.  Check the modem's manual.

I hope this is of some help.  --
