Result Codes - Multitech MultiConnect MTS2SA-T User Manual

Result Codes

The modem responds to commands from the DTE and to activity on the line by signaling to the DTE in the form of
result codes.
Two forms of each result code are available:
•
Short-form – a data-like numeric response (included in parentheses following the long-form). The short-form
is terminated by < CR> only with no preceding sequence.
•
Long-form – a "verbose" response, preceded and terminated by the sequence < CR> < LF>.
If result messages are suppressed, nothing is returned to the DTE.
The long-form result codes can be modified by the OEM through the .INF file.
The Verbose response may differ in some instances. Some modems may use V.90 terminology and some may use
V.92 terminology; however, the meaning of the message is the same:
V.92 Terminology
+MRR
+DR
+ER
+MCR
Note: An asterisk (*) in the Short Form column means that this Result Code is not active in V.22bis modems.
