SERIES II INTELLIGENT DATA/FAX MODEMS
If the $VD1 command is entered when in Auto-Answer mode, the
modem answers immediately upon receiving the first ring.
There is no disconnect message (NO CARRIER) if a normal connection
is made.
V.25bis Set-Up and Initialization
Before you operate your modem in the V.25bis mode, you need to make
sure it is set up properly (various RS-232 lines such as DSR and CTS act
as specified in the V.25bis standard). Setup involves proper DIP-Switch
settings and soft-switches (software controlled conditions).
