[comp.dcom.modems] CTS Datacomm Modems

This may be of more interest to the DDN side...

The WESTCOM DCSRM recently received a batch of Zenith 248s from the
standard contract, including the CTS Datacomm 2424ADH series modem.
Like so many others on the net, we have had to get some 9 pin modem
cables (HP 24542M) to get them to work with Crosstalk XVI on COM1.  We
have set up three modems so far, following the setup procedures
including those on page 63.  We used local mode to send the setup
string AT&D2&S1&C1&W<CR>, which does what setting DIP switches on a
real Hayes does.

When any one of these modems connects, to our DDN TAC or to the local
TELENET office, a barrage of garbage is displayed.  Both connections
are at 1200 baud, and some of the actual transmission is visible.  If
we swap out the CTS for a Hayes 1200 Smartmodem, all is well.

1. Is there a configuration setting we need to set?

2. Anyone else run into this?

By the way, this version does *not* have a speaker, which I miss for
troublshooting.
