Thanks, That's something to chew on for a while. Also, off list Brendan Moran offered to crack open the DOS program for me. He thinks either he or a friend of his might be able to see what it is doing when it sends the serial data. No word from him yet. This situation is looking kinda doubtful to me. My cousin and I managed to come up with a sloppy workaround by making a VB app that can send key presses to the DOS program. But that is just sloppy and weird. It would be much better to figure out the protocol instead. I guess we'll see if Brendan comes up with anything or not. -Dan ----- Original Message ----- From: "Marcelo Puhl" To: "Daniel Gliebe" Sent: Tuesday, July 09, 2002 11:11 AM Subject: Re: [EE]:Re: CRC Checksum - Can't figure it out - HELP > > See attached some info I got on the Internet.
