Yes, if you have a driver that references com 3.  I think you'll have
to recompile to do this - the PC hardware shares the com 1 / 3 interrupt,
so Minix handles two serial ports by default.  (Actually, IRQ 3 defaults
to the ethernet card unless you change it with DPETHO in bootmon's menu.)
I don't know of a serial port driver for minix that handles two ports
on one interrupt, tho' there probably is one; it won't have been ported
to 1.7, anyway.

There's no job control; there are various ways around, such as virtual
consoles, but I'm not sure how many of these have yet made it into
1.7.  Minix 386-vm uses X.
