receive and evaluate signs over UART

Please excuse my bad english
I want to receive a signs over the UART and evaluate it.
I currently use this solution (example):

If Usr.rxc = 1 Then
Z = Udr

Select Case Z

Case "3"
Call Up

Case "2"
Call Down

End Select

End If

This is not optimal - not all signs are detected -
i must repeat.
Is there a better solution?

Thanks Andreas

read the help and try the sample about serial
learn about Ascii code

Buffer ?
Speed of your program $baud ?
etc..

If I understand your question correctly:

Check how the wireless serial ESP-module is connected to the Arduino Mega 2560 and not missing any character on the Weatherstation. Using a serial buffer, reading complete lines finished with CR/LF. The exchange of 'pure ASCII-characters' at 9600 baud.

Perhaps an idea?
Have fun

Hello Andreas

I wrote this program
it sends a command to a solar inverter
it receives data back and works out what is sent
This may help you
