Winsock & Parallel Port

[RaulBecerra]

I am trying to sending data between two pc's by paralell port throug a "Laplink" type cable, a friend says that winsock support this comunication, is this true?, how can i make it?, Help me!!..

Only if the parallel port can support TCP or UDP which I seriously doubt. I have used the MS Comm Control in the past to communicate via serial ports. I have never tried to use the parallel port. I cannot find any reference to using the parallel port in MSDN in the Visual Basic topic area. You might need to get a third party OCX.

I also recommend a more complete search of MSDN and the KB on the MS web site.

I use a control called inOut.ocx.. try to get it from the net.. this will help u to use the parralel port..
I think this will be better than mscomm..

Actually, I wasn't suggesting using MSCOMM - it only works for serial ports - best used for modem communication - but does work for serial data transfer - very slow and length limited. I also wanted to point out that WinSock is TCP/IP or UDP based and won't work with a hard wired port like LPT1 - it is used with NICs or modem connections to a TCP/IP based network.

Your third part tool (or something like it) is exactly what Raul will need. Thanks for the suggestion - I will but it in my library also - you never know when you need something like that.

Thanks
