Subject: RE: new system and external dial modems
You may be experiencing a timing glitch due to the new 2742 cards.
Your ICF program (through the 2742) raises the OH (Off hook) signal when
it is ready to answer or initiate a call. The modem is supposed to raise
the CD (carrier detect) signal when it finds a dial tone. If you haven't
allowed enough time for this to happen, the 2742 or your program is
throwing the message. The old 2742's may have just been slow enough in
this turn-around that the settings didn't matter. You'll have to dig up
the documentation on how to set this. It will be in the same set up where
you set the maximum allowable RTS-CTS delay (Request to Send, Clear to
Send).
It's been a long time since I did RS232; kind of nostalgic.
