I've seen this so often that it is a wonder why it isn't archived

View from back of the computer:

	5       1
	  4   2
	    3

	1 - DTR (RTS) output
	2 - TD
	3 - GND
	4 - RD
	5 - DSR (DCD) input

How to build a pseudo-HWHS cable:

Port	Modem (DB-25)
  1 -->	4 (RTS), short to 20 (DTR)
  2 -->	2 (TD)
  3 --> 7 (GND)
  4 --> 3 (RD)
  5 --> 6 (DSR)
