4.3Result 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 video 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).

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.)
