Hi folks!

Can anybody show me how to implement an interrupt-driven input buffer
for the COM ports (preferably, in Turbo-C?  I am losing too much data
using polled input :-(.

Let's say I've defined a function

void interrupt interrupthandler()
{
 .....
}

which adds data to the buffer. How do I install the function as an
interrupt? How do I tell the UART to generate the interrupts?

If anybody has code to do this I would be really happy.
