Result Codes
When the MTA128ST-USB (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 below. 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.

Chapter 4 - AT Commands, S-Registers and Result Codes
Auto-synchronizing allows the TA to adapt to the client's network rate without
any need for the host to have its network rate predetermined. If S77=2
and a V.110 call is originated, then the network rate will be that of S76 ($MB).
Persistent DTR Dialing Delay
1 second
n=1-255 (1-255 seconds)
5 (5 seconds)
for the TA to dial are met, a delay of S80 seconds will occur before stored
number 0 is dialed. Some conditions include the TA not being in the
@CONFIG menu, not having a data call present at the time, and Persistent
DTR Dialing must be enabled. By default the TA will delay for 5 seconds
before dialing when all conditions are satisfied.
