S36 - LAPM Failure Control
Default: 7 (00000111b)
Bits 0-2
This value indicates what should happen upon a LAPM failure.
These fallback options are initiated immediately upon connection if S48=128. If an invalid
number is entered, the number is accepted into the register, but S36 will act as if the
default value has been entered.
0 =
Modem disconnects.
1 =
Modem stays on-line and a Direct mode connection is
established.
2
=
Reserved.
3 =
Modem stays on-line and a Normal mode connection is
established.
4 =
An MNP connection is attempted and if it fails, the modem
discount
5 =
An MNP connection is attempted and if it fails, a Direct mode
connection is established.
6
=
Reserved.
7 =
An MNP connection is attempted and if it fails, a Normal mode
connection is established. (Default.)

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.
Range:
0-255 seconds
Default:
20
S39 - Flow Control Bit Mapped Options Status
