yes, just call windows telnet.exe from CVI. Problem comes that you can
not create a CVI program which will simulate a user typing commands and
reading response. You can not get a handle to the process and read/write
from/to it like a file. ActiveX control will let you do that. You can
open a connection, and then do read/write and close when done. If all
you need to do is login
to a telnet port, send something, and process
output after closing connection, you can make a command line which takes
its input from a file and redirects output to another file. You call
this command line from your CVI program, and process the output file.
What I have also found is that you can also just use low level TCP (from
CVI) and open connection to port 80 (I guess for telnet). You will get
some garbage chars which you can filter. I am doing this right now and
it works.
For ping, you can also use windows ping program. Just call it from CVI
(as system command where you redirect output to a file) or launching an EXE.

I haven't used distinct tools with CVI. But they are one of the best
ones out there (I personally know the people who wrote the original code).
