Hello Daniel, In the Multipsk package (http://f6cte.free.fr), you have a file which name is RS232_EN.doc. It shows how to connect a RS232 9 pins port. It will give you idea. LPT port is not very used because it's not very easy to control from Windows (from DOS it was easy, by addressing directly the electronic ports). However on the Net, you have many other diagrams.

Use a serial port . not lpt . and surely not the 15pole connection . this is for your monitor You find the serial port at the backside and it is 9 pole in two rows . one with 4 and one with 5 If you have no serial port (only usb) there are several usb-serial transformers available for a few bucks If you have now a serial port you should use an optocoupler for triggering ptt on your trx . Just google psk31 modem or something and you will find lots of circuits Hope I could help Dg9bfc Sigi ------------------------------------------------------------------------------ Von: digitalradio@yahoogroups.com [mailto:digitalra...@yahoogroups.com] Im Auftrag von kg4kri Gesendet: Donnerstag, 29. Oktober 2009 02:36 An: digitalradio@yahoogroups.com Betreff: [digitalradio] lpt to com port assignment? Hello all, I am trying to set up my computer to key my radio rather than the el cheapo way of using vox. I have built a circuit to use the 25 pin lpt jack, but I do not know how to assign this jack as a com port. Most of the digital programs I use only specify com ports, not lpt. I do have a 15 pin connection, but I am not sure what the proper connection would be. I am obviously not very knowledgeable about computers, so any help is appreciated. Thanks, Daniel KG4KRI --... ...--
