running command from VB-Program on unix-server

I need to write a VB program, that runs under win nt, logs on to a unix server, runs an at-command and logs off again.

Is it possible and how can i do this.
Please help me.

Yes, you can do this.  I suggest you get ahold of an OCX that does rsh or telnet.  You can buy one here:

but you can probably find a freebee by searching the web.

You could also do it yourself using the winsock control, however, you will have to handle the protocol communications between your program and the UNIX server yourself... No small task!

If you want a telnet app in VB, look in 

there is a sample application there.
I don't know if it is a good answer for you. But here is something I did before.
Have your UNIX setup to allow the NT box to run rsh against the UNIX box.
The just shell out the rsh command in your VB program.
If you have more than 1 rsh command, you can dynamically create the batch file with all the commands that you need and use shell( batchfile, option ) in VB to run it. I did redirect the output to a file to check for expected return message or whatever to check for error.

I also found the following code to wait until the shell program is done.
taskID = Shell(strShellCommand, vbHide)
pHandle = OpenProcess(SYNCHRONIZE, False, taskID)
' Wait until DOS command has completed
ret = WaitForSingleObject(pHandle, INFINITE)
ret = CloseHandle(pHandle)

See if this is an answer for you.

Thanks for your comments. I am looking for an active-x control, if such a thing is available for this purpose.
