Comm Port to Ethernet

[norason]

We have a VB6.0 program that communicates with a device via a RS232 comm port.

We need to change the program to communicate via Ethernet. At the moment, we are using purchased Serial to Ethernet redirection software, but we can't justify the cost for several PC's, even with their OEM pricing.

Since I'm still fairly new with VB6 programmng, I don't know all the features/limitations. Can I modify our code to communicate via Ethernet? I'm not asking for code, just want to know if I should pursue research further.

Thanks,

ok, so I found out about WinSock, which apparently will allow communications over Ethernet. I'm busy researching that now.

Sorry if I bothered anyone.

Winsock is actually easier.
With comms you just listen and talk but with Winsock, the device usually becomes a client and the computer becomes a server.
They first connect through a connection process.

You need to find out how it connects and what sort of format the device sends data and tailor your computer Sub Winsock_Dataarrival() to suit.
