Serial communication to read single character

[Rachana]

Hi! List,
I want to read single character using serial communication(see the attached VI).
The initialization of the serial port is taken care.
TIA

I'm not sure I can understand you. If you want to read just one single character why can't you do so by just passing 1 to the Serial Read function as the number of bytes to read?

The diagram of above VI doesn't make to much sense to me I have to admit.

Rolf is right. If you want to read a single character just wire 1 to the byte count of the serial read. But I guess you meant differently.

According to the code, data loss is inevitable. "Scan string for tokens" returns the first token, in your case, seperated by "\s \t \r \n" even if multiple tokens are available.
