5.3.4 A sample Program (FICOM.H)
The following program is an example of a
C language program which helps users to
understand the data format and the data
interfacing method, and also to develop
their own programs.
[Interrupt Usage and Selection between COM1 and COM2]
#define COM1 0
#define COM2 1
/* Base addresses of serial ports */
#define COM1BASE 0x03f8
#define COM2BASE 0xx02f8
#define COMBASE (comport= =COM1) ? COM1BASE: COM2BASE)
/* Registers */
#define THR (COMBASE+0) /* Transmit Holding Register */
#define RBR (COMBASE+0) /* Receive Buffer Register */
#define IER (COMBASE+1) /* Interrupt Enable Register */
#define IIR (COMBASE+2) /* Interrupt Identification Register */
#define LCR (COMBASE+3) /* Line Control Register */
#define MCR (COMBASE+4) /* Modem Control Register */
#define LSR (COMBASE+5) /* Line Status Register */
