%A n Auto-Reliable Fallback Character
Where n is an integer between 0 and 127 indicating an ASCII
character (Default is 0, auto-reliable fallback character disabled).
Sets the ASCII character recognized as the auto-reliable fallback
character on the answering modem. In auto-reliable mode, when
the modem encounters an incoming auto-reliable fallback
character from the remote system, it automatically switches to
normal mode and passes the character to the serial port.
Auto-reliable fallback character recognition stops if the modem
receives a SYN character (decimal 22).

\A0 Sets block size up to a maximum of 64 characters.
\A1 Sets block size up to a maximum of 128 characters.
\A2 Sets block size up to a maximum of 192 characters.
