Serial comm - are 2 wires for TX only enough?

Make shure your fuse settings are correct before you program the pic and if you are going to use a 20Mhz oscillator remember to add the line DEFINE OSC 20

Hope it helps

Sure the DEFINE OSC 20 have to be inserted... but you have to modify the config fuse too... case not, it will neever ever work

Look at http://www.picbasic.co.uk/forum/showthread.php?t=543

you must set the OSC fuse to HS
