I'm making a tools to communicate with a barcode reader.
I use the MSComm control, but he don't support the x-modem protocol (I receive data but in the Xmodem protocol)
I have find a OCX that use this protocol, but it isn't free (400$).
Here is someone who can explain to me what the Xmodem protocol is and how can i use it.
Thanks

goto http://www.faqs.org I'm sure you'll find the protocol specs for Xmodem

Also, you should have got a barcode scanner which plugs directly into your PS/2 keyboard port. It's much easier to use; it acts like keyboard input (sends key codes).

Thanks a lot MrShickadance for the address. I've find what i search.
For your question, the barcode i have is a portable barcode. I can put a litle program in it (The barcode have a hard disk of 700ko). I use it for scanning product in plant shop, making consumption of this product, etc...

I see. That's pretty cool. Glad I could help. :)

Mr KWELL -
Did you succeed in writing a vB control? I'd appreciate seeing your source code as I'm trying to develop an XMODEM-1K control too ...
Many thanks!
(Anyone else know of this kind of source code??)
