[comp.sys.ibm.pc] Suggested pinout for RS422/485...

Hi,

I was wonder if there is a standard pinout for RS422/RS485 on the PC's
9-pin connector.  I have found a pinout on a card from a mail order
company named PERX's, but I wasn't sure if it was a standard or not.  I
would really appreciate any suggestions, or information on the subject.

Thanks,

Dan Yee
