AT Commands for CX81801/CX06833/CX81300/CX06827 Modems Reference Manual
102184B Conexant 3-19
X - Extended Result Codes
This command selects the subset of the result code messages used by the modem to
inform the DTE of the results of commands.
Blind dialing is enabled or disabled by country parameters. If the user wishes to enforce
dial tone detection, a "W" can be placed in the dial string (see D command). The
information below is based upon the default implementation of the X results table.
Table 3-2 indicates the messages which are enabled for each X value.
If the modem is in facsimile mode (+FCLASS=1 or 1.0), the only message sent to
indicate a connection is CONNECT without a speed indication.
