I use the Telnet VI's regularly, but I have not tried the FTP Vi's (But they do exist). As far as being available for Solaris, I can't help there... Sorry rick

Hi Jan. I see your message is fairly old, but I just faced the same thing today (Win98 and telnet) when trying to communicate w/an instrument that uses 10bT.
From Win98 I can open up Start|Run|Telnet and open a connection to my instrument and command and query it, but trying the obvious (TCP/IP functions: Open then Write then Read then Close sequentially) didn't get me very far, and left me w/o a clue as to what I was doing wrong.
Fortunately, in another message Armando García López wrote:

TalkPassive.vi basically seems to sets up and wait for another to connect to it. TalkActive.vi on the other hand provides the same functionality as win98's telnet, allowing me to interact manually (and successfully 🙂 with the instrument.
I'm all in a tizzy with this news and haven't implemented it in my real program but it's obvious that it's a cinch.
The only necessary non-obvious tidbit is that Telnet seems to wanna use port 23 (Win's telnet program offers port names (like "telnet") but not their numbers, and I don't know where that bit of information is available--If I hadn't found it around here by accident it would have taken a while to figure it out!!). ________________________________Marty

This interesting information can be traced to Internet RFC standards documents (http://www.faqs.org/rfcs/) and found all around the Internet by searching for the phrase "well-known ports."
Here's a very nice summary of TCP port assignments: http://www.isi.edu/in-notes/iana/assignments/port-numbers
You'll see that LabVIEW's VI Server has its very own registered port (3363), along with thousands of others out there, but low ones such as 23 have long been reserved for Telnet and other fundamental protocols.
