I have a bunch of interrupt driven serial code I wrote, which inits the
port, sets up interrupts and handlers, then queus all incoming and outgoing
data ... So far so good, except that I get one interrupt. I am doing an EOI
by sending 20H to port 20H, and OUT2 is asserted to enable 8250 interrupts.
My interrupt enable value is 3, and my mask value to the 8250 is 0xEA.

Any ideas? 


Thanx,
Steve
