Configuring Modem Signals
SIGNAL CONTROL and
DTRWAIT
DTR is asserted only if there is a solicited remote
connection.
(SIGNAL CHECK disabled) Solicited remote connection is established
regardless of the state of DSR. Reception of
asynchronous data is accepted once the connection
is established.
Port is logged out if DSR is deasserted after initial
assertion.
DTR is deasserted for 5 seconds minimum as a
consequence of a logout. DTR can only be
reasserted when a connection is accepted.
Reception of asynchronous data is not accepted
unless DSR and DTR are asserted.
SIGNAL CONTROL and
SIGNAL CHECK
DTR is deasserted for 5 seconds minimum as a
consequence of a logout; otherwise, it is always
asserted.
(DTRWAIT disabled) Port is logged out if DSR is deasserted after initial
assertion.
Reception of asynchronous data is not accepted
unless DSR and DTR are asserted.
Port status indicates “Signal Wait” if connections
cannot be accepted because DSR is deasserted.
Solicited remote connection is not accepted unless
DSR is asserted.
SIGNAL CONTROL, SIGNAL
CHECK, and DTRWAIT
DTR will only be asserted if there is a solicited
remote connection.
Port is logged out if DSR is not asserted within 60
seconds of connection acceptance.
Port is logged out if DSR is deasserted after initial
assertion.
DTR is deasserted for 5 seconds minimum as a
consequence of a logout. DTR can only be
reasserted when a connection is accepted.
Reception of asynchronous data is not accepted
unless DSR and DTR are asserted.
Port status indicates “Signal Wait” if connections
cannot be accepted because DSR is deasserted.
Solicited remote connection is not accepted unless
DSR is asserted.
