Myke - for what it's worth I've spent some 3 more wasted hours looking for the problem on the NEC laptop and I have learned that the serial port does work with other software like hyperterm and an old copy of mirror - typing characters to the Picstart plus however does nothing. I tried the Picstart Plus system on a friend's desktop machine and the same thing happens - can't detect the PSP on either of the serial ports on his machine either - again - all fifos, etc. set as suggested in the documentation. This thing is going back first thing in the morning - I've got projects to do and I'm afraid I just don't have the time to make a career out of trying to get someone else's hardware to work - especially when I buy it! I'd appreciate any pointers on another programmer that I can buy that tends to WORK? Cost is not much of a concern - keeping "my" customers happy is and there's some milestones coming up.... Thanks for your assistance.
