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).
