I don't know if anyone is aquianted with JRivers OFF.SITE but I would like to create a terminal emulator of this sort myself. Does anyone have any useful tips on this subject please?

Thank you Sheco. Do you have any more information on protocols etc that I need to read up on?
Oh, well this sort of depends on what you are trying to emulate.
The Winsock control lets you read and write data to a TCP/IP network.
If you want your terminal program to talk to the COM port then instead you can use the MS Comm control.
There are 3rd party versions of both Winsock and MS Comm that offer more features but see if you can't make the free ones work for you first.
As far as protocols I guess it depends on what you are trying to emulate. If you just want to write plain text line by line then that is easy enough.
On the other hand if you want to do full screen emulation so that you can host a "green screen" type application then you'll need something more advanced like VT-100 or other terminal control protocol.

I was thinking more along the lines of emulating the 'green screen' type application. I am not afraid to get my hands dirty with code but would not mind a point in the right direction.
ps. Cheers for the feedback!

The little Hyperterminal program that comes with windows supports these:
ANSI
ANSIW
Minitel
TTY
ViewData
VT100
VT100j
VT52
And it also has an Auto Detect feature.
Anyway, I found a web page about the old terminals:
Here is a page on that site that shows how the VT100 ueses escape sequences to move the cursor location on the screen:
And here is a site that seems to be dedicated to DEC's entire VT series. It includes some scans of the orignal docs:
If I were you I'd pick one and focus on that until I could get it working. You are certain to learn all sorts of things in the process... so I'd hold off on making the Grand Application Design until I did at least one of these bad boys... but thats just me.
