Technical support / Re: How to send an ASCII break from Com port?
« on: December 05, 2003, 01:06:21 AM »
An ASCII break is not a character, but rather a level on the transmit line. The break is a SPACE (logic 0) on the transmit line for a set duration, longer than the time for a character. In my case, I need to send a break of 100 mS duration to 'wake-up' my piece of equipment so I can send other commands to it over the serial line. Sending a NULL (0x00) won't work, as this is a valid ASCII character.
