&Q1
The modem will autoanswer and autodial with DTR
low, but will disconnect if DTR does not go high after
the time defined in S-register S25. When on-line, if
DTR goes low, the modem will wait for S25 time before
the call is disconnected.
&Q2 When DTR goes high, the modem dials the stored
telephone number held in location
N0 . When on-line, if
DTR goes low, the modem disconnects.
&Q3 DTR is treated as defined in ITU-T circuit 108/2. The
modem will not dial or answer when DTR is low. When
on-line, if DTR goes low, the modem disconnects.
&Q10
This conforms to V.24 108/1 (CDSTL, Connect DataSet
To Line). When DTR goes high the modem goes on-
line, and when it goes low it disconnects.
&Q14
The modem will autoanswer or autodial when DTR is
low, but will disconnect if DTR does not go high after
the time defined in S-register S25. If the modem is off-
line and DTR goes low, the modem will wait for the
time defined in S-register S25 before busying-out the
telephone line.
If the modem is on-line and DTR goes low, the modem
will wait for the time defined in S-register S25 before
disconnecting the call, and then after a further five
seconds will busy-out the telephone line.
The busy-out can be cleared by using the command
options
&B0
,
&T0
or by raising DTR for a time defined
in S-register S25.
