Terminal Adapter Result Codes

When the TA receives an AT command from the computer or terminal, it attempts to execute the command, then sends a status message to the computer or terminal that reports the result of the command. The TA provides you with several of these response messages, or result codes, which can be displayed on your monitor or intercepted and used by your communications software. Using the V command, you can select whether the result codes are terse (numbers) or verbose (words).

The TA’s result codes are listed in the following table. Note that the speed of an ISDN channel is always either 56 Kbps or 64 Kbps. CONNECT messages indicate the speed of the connection between the TA and your computer or terminal.
