lesbleus -- are you using USB at this point? If so, you have 3 possible places (I can think of) where comm. may be suffering:

- your USB/serial settings on your PC. Do a search and the forums and you will turn up lots of info about possible settings to your USB port that may help establish comm. correctly

- do you have the USB cable plugged in to the board and powered via USB BEFORE powering up the injket board? The way the pre-installed driver works, it looks for a connected and powered usb cable ONCE AT POWERUP -- if it detects a USB connection, it will use the usb and on-board usb driver for comm., otherwise it defaults to the TTL serial header

- that you are sending the correct vals from your terminal. Remember that "STX" is actually hex $02, ETC is hex $03, ESC is hex $1B. The ascii chars of your text string are straight ascii.

P.S. attached are two Stamp programs for downloading a bigger, bolder font to chars $80-$FF. Anyone who wants to use this -- be sure to check the serouts in the code -- this was setup for my revised driver that uses "!IJ" for a header, and dispenses with the prompt on the serial side. See comments in the code.
