I have heard a rumor that some *early* AT&T 6300's had the hardware for a
second serial port on their motherboard, but no connector.

I was wondering:

	Is this true?

	How can I tell if I have one of these machines?

	Can I just rig up a special cable to use it? And, if so,
		what is the pinout for such a connector?

(Please, no mail/postings about I/O cards, etc.)

Thanks in advance...
