ttyS3 (com4:) shares an interrupt with ttyS1 (com2:). Is com2: in use?
What does
setserial /dev/ttyS3 have to say?
You make need to change the interrupt, or disable com2: in your BIOS.
I believe mine was ttyS5 by default, and I need to use setserial to set
the ioport and interrupt. This information can be discovered from dmesg,
or from:
cat /proc/interrupts
cat /proc/ioports
Once you've come up with the right settings, you can add them to one of
the init scripts, say rc.local or rc.serial if you have it.
