Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes
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 TAs 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.
