My company just purchased a few ARK 2.4K Plus Dial modems, which I have
installed on our VAX/VMS system.  The modems work very well, except for
one small problem.  We have quite a few old-style Hayes Smartmodem 1200's
(the one's with only one phone jack in the back, and a volume knob) that
will be dialing into the ARKs.  These older hayes modems do not seem 
to recognize the valid carrier tone on the ARK, when the ARK is set to
autobaud down to 1200 baud.  Newer Hayes 1200 modems WILL work properly
with the ARKs, and the old-style Hayes will work with other 2400 baud
modems (such as the Hayes 2400s) on the VAX end.

Has anyone ever encountered a similar situation?  Any help would
be appreciated.

Thanks...
