Aside from not seeing initialization for the ports your code looks pretty good at first blush. You may need to declare your arrays as “static” to overcome some unknown compiler funny. I use 3 serial ports concurrently with no issues:

void main()
{
serBopen(9600);
serCopen(9600);
serDopen(9600);

serBrdFlush(); //
serCrdFlush(); //
serDrdFlush(); //

serBwrFlush(); //
serCwrFlush(); //
serDwrFlush(); //

// costates & such …

}
