Multi-Tech Systems, Inc. AT Commands for the MultiModem & SocketModem MT9234 Series (S000434H)
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> =
ERROR if <signal> ≠ 0 to 10 or <sig en> ≠ 0, 1 or <msg en> ≠ 0, 1 or <supp delay> ≠
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.

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.
