Hi all, I need to develop a hyperterminal like application in labview.I ve only lv6.1 version son cant open vis in higher versions. I a basic question 1) I need to create a sub VI using VISA ,then how to pass the resource name to the next Function from the subVI? There is a sub VI i created. it just initializes the serial port using VISA.i want to experiment this, to be used as a sub VI. I can pass the input resource name but how to get the outpt visa resource name from the sub VI...? Will the VI session will remain open..? normally i wire up duplicate resource name from visa initialize output to the next block but how to do it wen i want to put it inside a sub VI ? hope its clear now please put a jpg file of VI if possible (incase anybody is returning a VI) i cant go for higher versions becoz of license issues in my institution thanks Steve
