1 DTR drop is interpreted according to the current
&Qn setting as follows:
&Q0, &Q1, &Q5, &Q6: DTR drop is interpreted
by the modem as if the asynchronous escape
sequence had been entered. The modem returns
to asynchronous command state without
disconnecting.
&Q2, &Q3: DTR drop causes the modem to
hang up. Auto-answer is inhibited.
2 DTR drop is interpreted according to the current
&Qn setting as follows:
&Q0 through &Q6: DTR drop causes the
modem to hang up. Auto-answer is inhibited.
(Default.)
3 DTR drop is interpreted according to the current
&Qn setting as follows:
&Q0, &Q1, &Q5, &Q6: DTR drop causes the
modem to perform a soft reset as if the Z
command were received. The &Y setting
determines which profile is loaded.
&Q2, &Q3: DTR drop causes the modem to
hang up. Auto-answer is inhibited.
If &Q5, &Q6, or +FCLASS=1 is in effect, the action taken is the same as for &Q0.
