Hi,

I am writing a TSR to serve stuff coming from serial line on a PC. The
problem seems to be how to get the TSR awake when something comes from
the serial line. I have put the interrupt enable register to generate
an interrupt when receive data is on the register and I can see something
happening on the interrupt identification register on the 8250 but as I
understand I should get an INT 0C from the COM1 interrupt and I can t see
anything. I am using TP5.5 and Turbo Professional. Can anyone tell me
what I did forget or any other hints how to do it ??

Thanks
