Serial Read Sequence

[NormanSim]

Hi, I have some sequencing problems that need to seek for advice. Pls kindly refer to the attached VI and excel file. The method I doing is too tedious and need some advice to simplify it. Thank you in advance for the advice. Best Regards, Norman

The best advise I can give to you is to separate the low level activities from the higher level.

You can better use local vars than the awful construction of strings and panel control updates.

Another problem is looking only at the status of an IO operation and ignoring the wealth of information that comes from the error cluster.

remove the while from open and close and see what happens.

and always display the error status in a cluster.
