Delay Before Forced Hang Up
This register specifies the delay between
the modem’s receipt of the H command to
disconnect (or ON-to-OFF transition of DTR
if the modem is programmed to follow the
signal), and the disconnect operation.
Applicable to error-correction connection
only. This register can be used to ensure
that data in the modem buffer is sent before
the modem disconnects.
If S38 is set to a value between 0 and 254,
the modem will wait that number of seconds
for the remote modem to acknowledge all
data in the modem buffer before
disconnecting. If time expires before all data
is sent, the NO CARRIER result code will be
issued to indicated that data has been lost.
If all data is transmitted prior to time-out, the
response to the H0 command will be OK.
If S38 is set to 255, the modem does not
time-out and continues to attempt to deliver
data in the buffer until the connection is lost
or the data is delivered.
