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).
Note that the information below is based upon the default implementation of the X
results Table 1. indicates the messages which are enabled for each X value.
If the modem is in facsimile mode the only message sent to indicate a connection is
CONNECT without a speed indication.
