3-116
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. (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 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
