[comp.os.vms] DF112 modem and DMF32 controllers

vtcf@NCSC.ARPA (Williams) (11/04/87)

A while back I asked about a problem I was having trying to dial
out on a DF112 moddem using the SET HOST/DTE/DIAL... command.  Rummaging
through the release notes, it says that this won't work on a DMF-32.
The problem is that the modem sends a response character to the host when it
detects a carrier signal, but the DMF-32 drops any input until it sees the
carrier signal.  The release notes state that a workaround is to modify the 
example in SYS$EXAMPLES:DTE_DF03.MAR to perform a IO$_SENSEMODE!IO$M_RD_MODEM
 $QIO to check for a carrier signal.  I know nothing about MACRO, so this d
doesn't help me.  I asked someone here who knows MACRO, and he tried to do
this, but I get an access violation.  Has anyone done this before?  ALSO,
what's the difference between a DF03 and a DF112?  Any help will be greatly
appreciated.

Thanks in advance
