Hi DynamoBen,

What I understand from your explanation is that if there is nothing coming from Serin pin, then program will keep waiting until something starts coming in. So that the next instruction can be executed.

If my understanding is correct, then in Ryan7777's case, while there is nothing incoming, the next lcdout line will never execute; thus LCD will not show anything.

Am I right? I had something similar but I did not catch the reason. May be this is why.
