Chapter 10 − Modem Mode AT Commands, S-Registers, and Result Codes
Multi-Tech Systems, Inc. MultiConnect Serial-to-Serial Adapter User Guide (S000354A) 126
Register Unit Range Default Description
S95 0 Extended Result Codes Control. A bit set to a 1 in this parameter,
in conjunction with the W command, will enable the corresponding
extended result code. *
The +MR, +ER, and +DR settings also control S95 bits 2, 3, and 5,
respectively. The more recent settings of +MR, +ER, and +DR, or
host writing of S95 bits 2, 3, and 5, along with the W command
setting, determine the corresponding actual result code reporting (see
+MR, +ER, DR, and W commands).
Bit 0 CONNECT result code indicates DCE speed instead of DTE speed.
Bit 1 Append/ARQ to CONNECT XXXX result code in error-correction
mode (XXXX = rate).
Bit 2 Enable +MCR: XXXX result code (XXXX = modulation) and
+MRR: XXXX result code (XXXX = rate). (Also see +MR.)
Bit 3 Enable +ER: XXXX result code (XXXX = protocol identifier).
Bit 4 Reserved.
Bit 5 Enable +DR: XXXX result code (XXXX = compression type).
Bits 6-7 Reserved.
Note: Bits 2-5 are reserved in V.22bis.
S210 0–255 13 (0Dh) V.34 Symbol Rate. The bits in this parameter control V.34 symbols
rates and enable/disable V.34 asymmetric rates. This parameter is
used for diagnostic purposes only.
Default: 13 (0Dh) (00001101b)
Bits 0 -2 Selects the range of allowed V.34 symbol rates.
2
1 0 Symbol Rates (baud)
0 0 0 2400 only
0 0 1 2400 only (no 2734)
0 1 0 2400, 2800
0 1 1 2400, 2800, 3000
1 0 0 2400, 2800, 3000, 3200
1 0 1 2400, 2800, 3000, 3200, 3429 (Default.)
Bit 3 Enable/disable V.34 asymmetric rates.
0 = Disable asymmetric rates
1 = Enable asymmetric rates (Default.)
Bits 4-7 Reserved.
Examples
S210=13 Enable asymmetric rates with all symbol rates available
(Default.).
S210=5 Disable asymmetric rates with all symbol rates
available.
S210=8 Enable asymmetric rates with only 2400 baud available.
S210=11 Enable asymmetric rates with 2400 to 3000 baud
available.
* Register value may be stored on one of two user profiles with the &W command in all except V.22bis.
