connection.
CHARACTER LENGTH
+ 10 AT*C0 10-bit characters.
11 AT*C1 11-bit characters.
9 AT*C2 9-bit characters.
8 AT*C3 8-bit characters.
The character length includes start bit, data bits, parity, and
stop bit(s).
COMMAND SET
+ AT AT*I0 Modem accepts asynchronous AT commands.
V.25bis AT*I1 Modem accepts asynchronous or
bit-oriented synchronous V.25bis commands.
DUMP AT*I2 No command accepted. Modem ignores DTE data
in idle state.
Note: Only asynchronous V.25bis available on U-1496B.
DTE RATE
+ FIXED AT&B1 Modem serial port speed is always fixed
no matter what link rate (modem speed) is connected. If S44.6=1
and a non-ARQ connection is made, DTE rate follows link rate as
if &B0 is set.
FOLLOWS LINK RATE AT&B0 Modem serial port speed is set
in accordance with the link rate. If S44.6=1, the DTE speed is
fixed at 19200 bps when the link speed is above 9600, and at 9600
when the link speed is 7200, and at link speed when it is below.
Note: If you wish to keep your DTE rate fixed, you should choose
a buffered transfer. (see DATA FORMAT)
DTR OPTIONS
IGNORED AT&D0 Modem assumes DTR always ON, ignores the
changes.
108.1 AT&D1 An OFF-ON DTR transition causes the
modem to dial the number specified under the DEFAULT DIAL of the
MODEM OPTIONS submenu. An ON-OFF transition disconnects the modem
from the line.
+ DTR/108.2 AT&D2 Data Terminal Ready, an ON-OFF
transition of DTR will disconnect modem from line.
108.2 + RST AT&D3 Same as &D2 but DTR OFF also causes
reset from profile 0.
Note: Not all computers provide a DTR signal at their serial port connector. If such situations
arise you must use the IGNORED setting (AT&D0).
