There will be
a time when
the standard PeeCee lacks a RS232C port--unless added by the user with a
USB adapter--just like the way the situation with the floppy drive is
evolving.
Indeed, I think that time has already come, has it not?
Not that I know of. The dual-core Opteron nForce 550 system I just
built has one. (But only one.)
