PC to PC communication

[Learnin]

Hi everyone.

I have 2 PCs connected to each other with a RS-232 cable(Crossover cable using two DB9 female conenctors by connecting 5-5,  2-3 and 3-2 (pins 2 and 3 are crossed)). I intend to use just LabVIEW write data from one PC to the 2nd PC. The 2nd PC will then read the data(something like what I can do with Hyperterminal). I have read through many posts and have seen the "Basic Serial Write and Read.vi" and  "Advanced Serial Write and Read.vi" examples.

I have tried running the examples and nothing happens (nothing seems written and read). I am a beginner in LabVIEW and have no experience at all in this kind of communication at all and I do not understand the examples given and posts people have put up. I still do not understand how the VISA functions really work. 

In conclusion, I really need guidance on this. First of all, is it possible to accomplish the task with just the LabVIEW software and the DB9 connectors connected to the 2 computers which I have mentioned earlier? 

If it is possible, I really need guidance on how can I accomplish the task(in terms of programming in LabVIEW 8.6)? If not, what can I do on my side(either hardware or software)?

Any help that would answer my queries and solve my problems would really be much appreciated. Thanks in advance. 

Regards,

Jonathan

It's certainly possible to communicate between 2 pc's. If you have confirmed that it works with Hyperterminal, then VISA should work.

Attached are a couple of basic programs. One just does a write and the other just does a read. If these work, then you can modify them to do both a read and a write. Just place them on your separate pc's and before running, select the com port.

Thank you so much. I'll be sure to try them out! Hopefully it'll work this time. Thanks once again!
