AT command, for example ATV0 (this command enables shor t form
result codes).

The S registers control how the modem responds to your phone line
and computer. Generally, it is not necessar y to alter register values
when you are using communications software. The software
controls the registers as you issue commands. However, direct
access to the S registers allows you to customize and control your
modem for ever y application.
