Function COMSendChar

COMSendChar sends a character asynchronously using interrupts:

void COMSendChar(int Port, BYTE Data);

Parameters

Port

The port for sending.

Data

The data byte is placed in the send buffer to be transmitted by the interrupt handler as soon as the transmit register becomes empty.

Note that this function will typically return before the data is actually transmitted.
