LabVIEW 2017 and Telnet?

[CharlieD]

Hi All,

Sorry to rehash something that has been touched on in previous posts, but I did not really find a definitive answer to what I was looking for.  I am looking into the possibility of converting some code from Windows7/LV2012 to Windows10/LV2017.

Our division (interpret, me) inherited a test program that uses the Telnet functions from the 2012 Internet toolkit in the core of the test engine.  The LV code communicates with proprietary (not LabVIEW) test code resident in the unit under test, via Telnet.  I really don't want to gut the LV code and replace Telnet.  Another major issue is the UUT resident test code - it has a Telnet front end so it would need to be changed as well, and that code is under control of a different division.  Getting the UUT test code rewritten will most likely not happen.  Security and other such issues are not a problem since the code is only used in the labs during test.  I know that Telnet is dated technology, no longer supported and that using it is frowned on, but I am pretty much stuck with it.

The big question is, does anyone have a feeling as to whether or not the 2012 Internet toolkit install and work with LV2017?

TIA

Charlie

Hey Charlie,

My good friend danny_t recommends using the standard VISA resources as a method of communicating over telnet without the deprecated library. You can check out his discussion here and most likely PM him for further information on the subject. 

Best of luck,

I just use the TCP functions.  As long as the option codes are ignorable and you only use ASCII data, this works perfectly.  One of these days I will have time to write my own library to include at least some of the option codes...
