3.3.3.30 S38 - Delay Before Forced Hang Up
S38 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
parameter can be used to ensure that data in the modem buffer is sent before the modem disconnects.
1. 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 indicate that data has been lost. If all data is transmitted prior to time-out, the response to
the H0 command will be OK.
2. 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.
