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 disconnects.
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. (

Bits 3–7 Reserved
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 register
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 sec-
onds for the remote modem to acknowledge all data in the modem buffer before dis-
connecting. 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
Default: 0
Bits 0–2 Status of command options
0 = No flow control (
Default
)
3 = RTS/CTS
4 = XON/XOFF
5 = Transparent XON
Bits 3–7 Reserved
