Status and Connection Messages

Appendix H 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.
