Serial port

[SAL2005]

Hi,

I am new to labview and need help.

I am trying to talk to the serial port in my computer through labview. I have labview installed and when i add the visa resource button on my labview program, I dont see any com ports.. I only see ASRL.?????

Can anyone suggest me how to talk to my serial port with labview and what does ASRL means..

Thanks..

Which version of VISA and which OS  do you use?

OK, you expect COM ports, so it's Windows     ASRL is NIs platform indepentend name for serial communication ports

Use the MAX to set Alias names COMX .... should be done automaticly by newer versions of VISA. (Or edit visaconf.ini by hand)

(Click HELP- Find Examples ..  search for serial and have a look at the basic ... sample vi )
