padSetPortIrq
Sometimes it may be necessary to manually specify the interrupt request numbers used when referring to a communications
port.
padSetPortIrq
provides this ability. This function works only when the library is in an “off” state (i.e., before
padOn
()
or after
padOff
()). This is not normally needed, however it may be useful in some situations.
Note: This function is available in the DOS version only!
Syntax
DOS: int padSetPortIrq(
int Port,
int Irq
)
Parameter
Description
Port
1 = COM1
2 = COM2
3 = COM3
4 = COM4
Irq
The value to be used as the port interrupt number
Returns
Returns TRUE if the port specified is legal and library is “off”, otherwise FALSE.

before
padOn
/

or after
