Downloaded from Elcodis.com electronic components distributor
Chapter 1 – AT Commands, S-Registers, and Result Codes
OK if <v8o> = 1, 6 and <v8a> = 1, 5 and <v8cf> = 0 to FF and <v8b> = 0 to 2.
ERROR if <v8o> ≠ 1, 6 or <v8a> ≠ 1, 5 or <v8cf> ≠ 0 to FF or <v8b> ≠ 0 to 2.
OK if <signal> = 0–10 and <sig en> = 0, 1 and <msg en> = 0, 1 and <supp delay> =
0,1.
ERROR if <signal> ≠ 0 to 10 or <sig en> ≠ 0, 1 or <msg en> ≠ 0, 1 or <supp delay> ≠
0,1.
Send V.8 bis Signal and/or Message
Use this command to send a V.8 bis signal or message from the local DCE. This
command is only supported when V.80 is enabled.
AT+A8T=<signal>,<1st message>,<2nd message>,<sig en>,<msg en>,<supp delay>
0 None
1 Initiating Mre.
2 Initiating MRd.
3 Initiating CRe, low power
4 Initiating CRe, high power
5 Initiating CRd
6 Initiating Esi
7 Responding MRd, low power
8 Responding MRd, high power
9 Responding CRd
10 Responding Esr
0 Enable detection of initiation signals. Default.
1 Enable detection or responding signals
Disable detection of messages. Default.
1 Enable detection of V.8 bis messages
No delay inserted. Default.
1 Insert 1.5 second delay between transmitted V.8 bis signal and the subsequent
V.8 bis message
+A8T? Reports current or selected values.
+A8T=? Reports supported parameter values.
OK if <signal> = 0 to 10 and <sig en> = 0, 1 and <msg en> = 0, 1 and <supp delay>
= 0,1.
ERROR if <signal> ≠ 0 to 10 or <sig en> ≠ 0, 1 or <msg en> ≠ 0, 1 or <supp delay> ≠
0,1.
Select V.42bis or V.44 Data Compression
Use this command to configure the available compression algorithms. The <v42bis>
parameter enables or disables the V.42 bis and the <v44> parameter enables or
disables V.44. This command works in conjunction with the %C command and the
result of either the %C command or the +DCS command replaces the current data
compression configuration.
AT+DCS=<v42bis>,<v44>
0,0 V.42bis and V.44 data compression are both disabled.
0,1 V.42bis is disabled; V.44 data compression is acceptable.
0,2 V.42bis is disabled; V.44 only when connected to a V.92 server.
1,0 V.42bis is acceptable; V.44 data compression is disabled.
1,1 V.42bis is acceptable; V.44 data compression is acceptable.
1,2 V.42bis is acceptable; V.44 only when connected to a V.92 server.
+DCS? Reports current or selected values.
+DCS=? Reports allowed parameter values.
OK if <v42bis> = 0, 1 and <v44> = 0 to 2.
ERROR if <v42bis> ≠ 0, 1 or <v44> ≠ 0 to 2.
