S38 Delay Before Forced-Disconnect
This register controls how long the modem waits, after receiving the ATH command or loss of DTR, before
it disconnects from the telephone line. When connected in an error-corrected mode, you can use this register
to ensure that all data is transmitted from the modem's buffer before the modem disconnects.
If you set S38 between 0 and 254, the modem waits that number of seconds for the remote modem to
acknowledge all data before it disconnects. If you set S38 to 255, the modem waits indefinitely for the
remote modem to acknowledge all data.
Range: 0 - 255 seconds
