re:  "i have a hp 2623a terminal and havent had any luck getting it hooked
     up to a modem due to the fact i have no manual for it.  does anyone
     have an extra manual for one of these terminals for more importantly a
     diagram for a modem cable?"

Although the HP 2623A is no longer in production, the manuals are still in
print, and are:

   02623-90001  Users Manual        $ 16.00
   02622-90008  Reference Manual      23.00
   02622-90007  Service Manual        30.00
    5957-9918   Cabling Manual        17.00

The datacomm pinouts are as follows.  This also describes the HP 13222N or
5061-4215 U.S. modem cables.  Only those lines marked with an asterisk (*)
are generally needed for use with port selectors or real modems.
