Thanks for the reply... Sorry, really didnt explain too well. This is an 8 bit packet sent over rs-232. 3 bits of it are data and 2 crc of that data. (made mistake writing it down) Having various data values and the relevant created crc's, how do I go about finding what seed was used to create...

Not truely a tcp/ip question so apologies. Have a serial connection that is sending data as follows: 'A packet header byte is sent followed by data pertaining to that packet followed by a 16 bit CRC.' Now the problem is, I cant seem to reproduce the same CRC. An example of packet sent (hex)...

sorry, hadn't written the program to convert it into Hex properly. :)

Thanks idarke. That pretty much along the lines of what I am doing. :) And thanks IonFilipski, I downloaded one of said programs and am now receiving the 'commands sent'. I have one problem now tho, using the serial monitor program I have found out what the baud rate is and how many data bits...

Now first I apologise if this post is not relevant to this group, but I couldn't find a topic it fitted in, and as I will be doing it in java, thought i'd post it here. If there is one better suited, please point me in the right direction. :) I have a device from 1987 (a Q-Zar lasertag system...

Thank you! :)

I want to write a program which listens to the parallel port and prints on screen any data that is sent to it. I am trying to decode a device and what commands it sends/receives to work. How would i go about this? Thanks! :)

That excellent, thanks folks, I will give them a try this afternoon. :)

Just getting back into Delphi after about 4 years away, and have a few probs trying to remember a few bits when working with databases. 1) When I return an SQL statement, giving me a single column of x rows, how can I 'export' that as a string array? 2) As 1), but with more than one colum can...
