For reference - I haven't really followed much of this thread but I can=20 possibly save you some time in future debugging and testing with serial=20 devices and programming. I do a lot of work with serial devices and often away from my workshop. Thi= s=20 usually means not having access to the hardware I'm working on so generally= =20 emulate the inputs. On a laptop with zero serial ports, this can be quite an interesting task. = I=20 found the following software absolutely invaluable : http://www.eterlogic.com/Products.VSPE.html It lets you set up virtual serial ports on your PC but more importantly it= =20 lets you virtually link the two together. You can then have a couple of=20 applications talking to each other on the same PC. Its also FREE !!!!
