| 586578 | 2007-08-31 06:16:00 | I am attempting to wire a null modem cable to connect the ECP parallel ports of my 2 computers (just for the exercise and at minimum expense). I found an old printer cable with a male DB25 on one end and a Centronics on the other which I have cut off to replace with another male DB25. The null modem pin connection info from Loopback says pin 1 is Frame Ground (connection optional). However, info obtained from Pinouts.ru says Pin 1 on an ECP parallel port is HostClk Strobe. The info from both these sources appears contradictory. Question 1: Can I leave Pin 1 unconnected? 6 data pins crossover to their opposites and the last (Pin 7) is signal ground to the same pin number at the other cable connector. Question 2: Is any software needed to make it work? Further info: both computers XP Home SP2. Thanks... |

| 586580 | 2007-09-01 02:27:00 | "Frame Ground" is a serial "signal" line name. :D DB25 connectors were used for serial communications before IBM used them for a parallel port (and Apple and others used them for SCSI). ;) The tradename for the parallel cable used for this file transfer mode is "LapLink". It's not a "null modem'. A null modem is used for a similar serial connection. |

| 586581 | 2007-09-01 08:41:00 | Laplink is just a company that specialise in computer to computer transfers by Serial, Parallel and USB cable. Other software also use this method. eg. Softcopy "A null modem cable allows you to connect your PC to another nearby PC or serial device using its modem protocol" A USB cable from likes of Dick Smith comes with a driver that also allows PC to PC transfers. Pin'ing out a Serial or Parallel cable should not be too hard and from memory Windows should have the software to enable it. Windows 95 used to so I assume Win98/XP/Vista still does. Called Windows "Direct Cable Connection" |

If I wanted to access my internet connection from my Guest notebook thru my Host PC, do I need special software? The DCC connection has been setup between the two computers. :-) |
