  Few PC ports can support sync protocols, so you will need a
  sync board.    

  If your baud rate is 9600+, I would recommend a 'smart" sync
  board rather than a dumb one.  The diff is that the smart
  boards have a small processor to do most of the SDLC....the
  dumb ones cause a lot of problems and have pretty poor
  performance.  Look for a '186 or '960 on the board.  

  This is just about the largest PC commo plug in product family
  for SNA....3270 emulation.   The selection is so large that
  specific recommendations are difficult.   
   
  SNA compatibility varies between products....these do a
  LOT of SNA....

  Check with:

    o  DCA at 800-348-DCA1.   

    o  Rabbit  (Malvern PA?)  check also CTI in RAleigh NC.

    o  3COM   Santa Clara Calif.

    o  CLEO   

    o  EICON.  212-265-3220  (nice user interface....uses 
			      Windows 3.0 and can emulate
			      the 3279 Color Graphics terminal)

You should be able to get most of these from local computer
stores...
