Description
On Hook Time:
encounters a flash dial modifier (!) in the dialing string.
Disonnect Inactivity Timer:
disconnecting when no data is sent or received. A value of zero disables the timer.
Applies to asynchronous operation only.
LAPM Failure Control:
LAPM negotiation failure. These fallback options are initiated immediately upon
connection if S48 is set to 128. If an invalid number is entered, S36 acts as if the
default value has been entered. (See S48.)

Delay Before Forced Hang Up:
the H command to disconnect (or high-to-low transition of DTR if the modem is
programmed to follow the signal) and the disconnect operation. Applies only to
error-correction connections. This register can be used to ensure that data in the
modem buffer is sent before the modem disconnects. If S38 is set between 0 and
254, the modem waits for the remote modem to acknowledge all data in the buffer
before disconnecting. IfS38 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.
Data Compression Control:
136 Error correction without compression.138 Error correction with compression.
V.42 Negotiation Control:
An invalid value is treated as a 128 value.

Call Failure Reason Code:
a value is written to this register to help determine the reason for the failed
connection. S86 records the first event that contributes to a NO CARRIER
message. Use the S86? command to read the value.
