The problem is probably that you've got an IDE disk that's interrupting the CPU all over the place. If its IRQ is more important than the serial ports IRQ, and the disk interrupts happen _really_ often, the serial port doesn't get serviced in time. By the time the serial interrupt routine is called, the UARTs flag says "you missed something!". Of course changing the UART to IRQ 2/9 may kill your hard drive ! The real solution is to turf your IDE drive or at least get a SCSI drive for the filesystem with the hugh throughput. -- Brian <brian@awfulhak.demon.co.uk> Don't _EVER_ lose your sense of humour....
