Hi there,

Anybody know how to write VB program to read/write parallel port over internet or LAN? Thks.
 

You will need a server program running on the computer with the parallel port and a a client program to talk to it.

Server listens on a TCP port, client conects to it. Make up a simple protocol to send commands to the server.

Read the communication area over at visual basic forums including the sticky post with FAQ's.

Operation over the internet may require configuring any firewall and connection sharing system in the way.
 

It is a little like the network share printer. I think it is easy to implement.
