S38 – Delay Before Forced Hang Up
(Not stored with the AT&W command)
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. This register can be used to ensure that data in the modem buffer is sent before the modem
disconnects. 255 makes the modem stay connected until the buffer is empty, or the carrier is lost.
