AT#O Buffer Overflow
The #O command decides what happens when your modem buffers fill and can no longer accept
data. This will occur if data is received faster than your computer or modem can accept it.
+ The #O command is not supported when a variable speed mode connection is
established.
Options
AT#O0 n Characters are ignored if the modem buffers overflow.
AT#O1 Modem disconnects if the terminal buffer overflows (that is, data from the
computer to the modem). S Register 42 (the Disconnect Reason) is set to 10.
AT#O2 Modem disconnects if the line buffer overflows (that is, data from the line to
the modem). S Register 42 is set to 9.
AT#O3 Modem disconnects if either buffer overflows. S Register 42 will be set to 9
or 10, depending upon whether the line or terminal buffer overflowed.
