Does the kernel interrupt configuration support those interrupt lines
which are used by many internal modems when dip-switched to COM3 and
COM4?  If I remember right, the only interrupt lines supported for
COMs are those for COM1 and COM2 and if you want to use COM3 or COM4,
you have to reconfigure your kernel interrups somehow.  I'm not sure
about this, but if /etc/serinit (mkdev serial) doesn't help, this
may be the problem.
