2-Wire Dial Dumb Mode (Quick Setup 5) - Black Box 32144 Manual

Synchronous V.25 bis Operation
In synchronous applications, the
V.25 bis commands can be used
to facilitate computer-controlled
operations. Synchronous bit-
oriented operation uses High-
Level Data Link Control (HDLC)
formatting. In synchronous
character-oriented operation,
messages are framed by synchro-
nous start-of-text and end-of-text
characters, with the start-of-text
character preceded by two
synchronous (SY) characters.

Dumb mode is used primarily
for manual call origination, and
answer-only applications, and in
conjunction with certain dial back
security systems that use MI/MIC
signals to place the modem on-line.
(If you need to configure the
modem for MI/MIC use, refer
to Appendix C.) For additional
information on Dumb mode,
refer to Chapter 4.
Answering a Call Automatically
After the Quick Setup for 2-wire
dial Dumb mode has been selected,
the modem is configured to
automatically answer incoming
calls. The only other requirement is
that the DTE must provide the
DTR signal (TR on the EIA status
screen) to the modem or DTR
must be set to TRUE (using the
modem's DTR from EIA option
screen).
