<Take me.>


Does anybody out there know about using Hayes-compatible autodial
modems from a VMS system?  The problem is actually not with the
modem, but with the DEC terminal driver.

We are using a terminal emulator program under VMS to dial out of
our VAX-11.  Unfortunately, on a DMF modem control line, if there
is no carrier detected, then no echoing takes place.  This makes
sense to protect the system from noisy lines, but it means that
we have to dial "in the dark", so to speak.   VMS will echo nothing
until the connection has been made.   We *COULD* flip a dip-switch
in the modem to force carrier, but then we lose the modem control
logout function, and that is not acceptable.  Does anyone out there
know how to force VMS to echo even when there is no carrier?

Thanks in advance,
