I see that the Parallax board does sport an FTDI chipset so that shouldn't be a problem.   I had read that the driver board for the Inkjet also has a serial Interface.  The reason I asked how it was being connected to the PC is to confirm what port was being used on the driver board.  Although unlikely, I wanted to rule out some third party USB to serial converter as being part of the problem.  Sould be a non-issue here.

With the lack of flow control there is another little useful setting within Hyper Terminal if you want to use it to send text files to a device.  If you want to send a LARGER text file you can sort of throttle it back to give the other end a bit time so it will be ready for the next character.  You do this by specifying a couple of delays.  You can add a tiny delay between characters and also at the end of a line.  You can access this in HyperTerminal by:

- File
- Properties
- Settings Tab
- ASCII Setup..

Here you can tweak all sorts of settings.  If you find that without flow control you are sendind data too fast just try adding a short delay and see if that helps.  It is a very useful thing to remember if you have to talk to older equipment.  For those that use Linux I believe MINICOM also has similar settings.
