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 num-
ber 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 estab-
lished. (Default)
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 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
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
