MODEM
9-25
S Registers
S82 = 3 Expedited: Modem sends a break immediately; data
integrity is maintained both ahead of and after the break.
S82 = 7 Destructive: Modem sends a break immediately;
data being processed by each modem at the time of the break
is destroyed.
S82 = 128 In sequence: Modem sends a break in sequence
with any transmitted data; data integrity is maintained both
ahead of and after the break. (Default.)
S86 Call Failure Reason Code
When the modem issues a NO CARRIER result code, a value
is written to this S register to help determine the reason for a
failed connection. S86 records the first event that contributes
to a NO CARRIER message. The cause codes are:
Range 0, 4, 5, 9,12,13, or 14, Default: -
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
S91 PSTN Transmit Level
Sets the transmit level, in dBm, for the PSTN mode. In some
countries, this level cannot be changed and there are checks
to prevent transmit level change.
Range: 0 to -15 dBm, Default: 10
