Hardware Configuration
RTCom expects the following IRQ settings for COM1 to COM4:
| Port |
IRQ |
| COM1 |
4 |
| COM2 |
3 |
| COM3 |
4 |
| COM4 |
3 |
Please make sure that your serial I/O board actually supports interrupt sharing. If it does not, you cannot use COM1 and COM3 or COM2 and COM4 simultaneously in interrupt-driven mode. COMSetIRQ may be used to define different IRQs for ports COM1 .. COM6. Interrupt sharing can be defined for any IRQ, but only for port pairs COM1/COM3 and COM2/COM4. Best performance is achieved when every port has its own IRQ.
