This problem usually happens if you have two serial ports using the same
IRQ but which are on different cards. Normally ttyS0 uses IRQ 4 and ttyS3
uses IRQ 3, so one wouldn't expect this to be your problem. You'll have to
verify this with the setserial command. If this is your problem, you'll
either have to change the IRQ of at least one of your two serial ports, or
get a multi-port serial card which has a shared status register. I,
personally, use an 8 port BOCA board, on which all 8 ports share the same
IRQ, and have no problems with it.
