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: [email protected] [mailto:[email protected]] Im Auftrag von kg4kri Gesendet: Donnerstag, 29.

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 --... ...--
