Table 3 summarizes the possible parallel port pins for the serial ports and their clocks.
4.2.1.1 Using the Serial Ports
The receive lines on the RCM4200 serial ports do not have pull-up resistors. If you are
using the serial ports without a receiver chip (for example, for RS-422, RS-232, or RS-485
serial communication), the absence of a pull-up resistor on the receive line will likely lead
to line breaks being generated since line breaks are normally generated whenever the
receive line is pulled low. If you are operating a serial port asynchronously, you can inhibit
character assembly during breaks by setting bit 1 in the corresponding Serial Port
Extended Register to 1. Should you need line breaks, you will have to either add a pull-up
resistor on your motherboard or use a receiver that incorporates the circuits to have the
output default to the nonbreak levels.
The Dynamic C RS232.LIB library requires you to define the macro RS232_
NOCHARASSYINBRK
to inhibit break-character assembly for all the serial ports.
#define RS232_NOCHARASSYINBRK
This macro is already defined so that it is the default behavior for the sample programs in
the Dynamic C SAMPLES\RCM4200\SERIAL folder.
