Sending 1 byte at a time

[KowdTek]

I have a device that takes byte by byte string command and I'm using the attched file to do this but somehow seems not to work. If I send X66\r, I'm only getting X & 6 back.

Note that sending the same command via hyperterminal works just fine. So what is the best way to do this method using LabVIEW?

Thanks!!!

What do you get if you dont use a for loop?

[RavensFan]

Do you want to send one byte at a time like your subject says or read one byte at a time like your code shows?

Why are you using the bytes at port and VISA read the way you are?

You might be expecting 3 bytes back, but if there are only two bytes at port at the instant that function is read, then the while loop only runs 2 times, and you only read 2 bytes in total.

Oppps... the attached code was misleading...

Just got an update from our software engineer and what we want is to send the string one at a time.. so how do I set it in that manner.

Thanks!!

Example in this thread works for me...
