The AT-compatible I/O address can only be set once for each COM port of an
automation computer (including those permanently installed in a programmable
module).

The COM ports (COMa and COMb) of the UART 16C552 can be addressed from
offset addresses 10

H

 or 18

H

 in accordance with component specification 16C552.

The following data formats can be set in the IF 962-COM interface submodule:

Data bits:

5 bits, 6 bits, 7 bits, 8 bits

Parity:

Even, odd, disable

Stop bit:

1 bit, 1.5 bits, 2 bits

The following transmission speeds (transmission rates) can be set in the
IF962-COM interface submodule:

AT-compatible transmission speeds and transmission speeds up to 115.2 Kbps.

Please note that a safe level of transmission speed depends on factors such as
cable length, cable type, and environmental interference.
