Status and Connection Messages
Status and Connection Messages
If the UTA 220 is in command mode, and the DTE sends it a
command, the UTA attempts to execute it and then sends a
status message (if the option to do so is enabled) to the DTE.
If the command was a dial command, then the message is called
a connect message.
Status messages may also be sent as the result of other
conditions detected by the UTA 220.
The messages sent depend on the message configuration
options in effect: worded messages vs. number codes (ATV
command) and normal vs. extended messages (X and W
commands).
Status and connect messages, number codes, text messages,
and meanings are as follows.
