Chapter 5 - Command Mode

Multi-Tech Systems, Inc. MT2834BA/BL Series User Guide

5.3 Result Codes

The Command mode provides you with several responses, or “Result Codes”, that can aid you in

Command mode operation. These Result Codes are displayed on your monitor.

You can choose result codes that closely match those of the standard AT command set, or choose

enhanced function result codes that have been used in Multi-Tech modems ("Multi-Tech" responses).

The &Q command selects which result codes will be used.

You can choose to have these Result Codes displayed in either “verbose” (full words) or “terse”

(digits) format. This is controlled by the ATV0 (terse) or ATV1 (verbose) commands. The modem

defaults to verbose format.

AT&Q0 selects Multi-Tech responses with Reliable/LAPM/Compression modifiers. The terse

response code for CONNECT 2400 is 9. AT&Q1 selects Standard AT command set responses. The

terse result code for CONNECT 2400 is 10.

The following tables define the result codes generated by the &Q command (refer to Appendix G for

Result Code Summary).

correction on, LAP-M (or L) is added to these result codes. With data compression on,

COMPRESSED (or C) is added. (Note these "Extended" Result Codes are displayed when your

modem is set up to do so with an X1, X2, X3, or X4 command.)
