4 - 44 Trumpcard 14400/28800 Modem
Section Four
S48 — V.42 Negotiation Action
Range 0,7, or 128
Default 7
The V.42 negotiation process determines the capabilities of the remote
modem. However, when the capabilities of the remote modem are known
and negotiation is unnecessary, the process can be bypassed if desired.
If an invalid number is entered, it is accepted into the S register, but S48
will act as if 128 is entered.
S48 = 0 Disable negotiation; bypass the detection and
negotiation phases; and proceed with LAPM.
S48 = 7 Enable negotiation.
S48 = 128 Disable negotiation; bypass the detection and
negotiation phases; and proceed at once with the
fallback action specified in S36. Can be used to
force MNP.
S86 — Connection Failure Cause Code
Range 0, 4, 5, 9, 12, 13, or 14
Default 0
When the modem issues a NO CARRIER result code, a value is written to
this S register to help determine the reason for the failed connection. S86
records the first event that contributes to a NO CARRIER message.
The cause codes are:
S86 = 0 Normal disconnect, no error occurred
S86 = 4 Loss of carrier
S86 = 5 V.42 negotiation failed to detect an error-correction
modem at the other end
S86 = 9 The modems could not find a common protocol
S86 = 12 Normal disconnect initiated by the remote modem
S86 = 13 Remote modem does not respond after 10
re-transmissions of the same message
S86 = 14 Protocol violation
