If that doesn't work, look at the keyboard setup menu (F3 does setup) and make sure that a key is assigned to be BREAK. F5 is the solution.

That's not what I want. You need to send a break. Most serial terminal programs (or real serial terminals) will have a way to send a break.

If you're good with wires, you can try this: briefly ground the TX signal. A break in rs232 is sent by holding the signal low from start bit through when the high stop bit would be expected. You have to ground the signal going into the inverter chip and not the signal on the wire, which is at 12V and inverted. The inverter chip is usually a small Maxim brand part. Google for its pinout and use a volt meter to trace the wiring. -- Nicolas Dade -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
