Hi Padu, I do this all the time. I use a DB9 to RJ45 adapter and a CAT5 patch cable. You need RX,TX,GND. I buy the adapter at Frys for a couple of bucks Fry's pn: 2402340, it's made by Pan Pacific.

Right now, on my development board I have a PCB DB9 female, that makes the PC connection using a standard DB9 male - DB9 female 1-to-1 cable. The thing is my device is too small to have a PCB DB9 female, so I was thinking of other types of connection. I'm only using the Rx and Tx lines (do I need to have a cable with more than 2 wires?) so I was thinking of a smaller connector in the device (RJ11 for example) and providing a RJ11 male to DB9 female cable with my device, but I couldn't find such cable on mouser. Is this so out of the normal that I'll have to customize a cable for this application or do you know a manufacturer that makes such a cable (or one that uses similar small sized connector on one side of the cable) TIA Padu -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
