Note: On all ProLinx modules, data from the application port on the main board, serial Port 0, is not
buffered. Packets go directly to and from the serial chipset to the processor. This has the potential
to cause the serial communications to become erratic at baud rates above 38,400 baud.
ProLinx modules with 4 serial ports have a separate serial interface board for serial Ports 1, 2, and
3. These serial ports are buffered and can handle communications up to 115,200 baud.
