These bits set the format of serial
port communication data in the
free-port mode: 7-8 = number of
bits of data, N = No parity control,
O = Odd parity, E = Even parity, 1,2
= number of stop bits.

Bit 8
Bit set to “1” enables the free-port
mode.
“0” returns the serial line control to
the protocol selected during the
programming phase.

Num. Byte in EXP1 reception buffer
SM44 1044
Num. Byte in COM2 reception buffer
For each serial line, this word contains the
number of valid characters present in the
reception buffer. It is used in the free-port
mode to control the number of characters
received. Anything written to this word will
set the value to zero, thus emptying the
reception buffer.
