I use a handler interrupt with gcc in djgpp for control a serial port
comuncation and when I write a large buffer of data to the disk in a
file it apear overun erros in the receiver of the serial port. It seems
that when a program call a dos service switching to real mode  the
interrupts are disabled.

Somebody know if is posible to avoid this problem.

Thanks.

Francisco
