Function RTPCMapUART

This function maps and enables all required resources to use a serial port PCMCIA card:

void RTPCMapUART(int Socket, WORD IOBase, int IRQ);

This function should be called after an application has verified that a serial port card type has been inserted.

Parameters

Socket

Specifies the socket of the card to map.

IOBase

Specifies the I/O address at which the serial port should appear.

IRQ

The interrupt to be used by the port to signal interrupts.

For example, if you want to use the port as COM2, use:

RTPCMapUART(Socket, 0x2F8, 3);

Function RTPCMapUART's source code is:

void RTPCMapUART(int Socket, WORD IOBase, int IRQ) 
{ 
   RTPCSetConfigRegister(Socket, RTPC_CFGREG_OPTION, 0x41); 
   RTPCUnmapCIS(Socket); 
   RTPCMapIOWindow(Socket, 0, IOBase, IOBase, 8, RTPC_IO_WINDOW_8BIT | 
                                                 RTPC_IO_WINDOW_TIMER1); 
   RTPCEnableIRQ(Socket, IRQ); 
}
