Switch case and software serial

Using Arduino Project Guidance
7

Totally understood, but my goal was to exit the main loop and enter the VIPassing loop... if only one character got lost in the transition that would be fine, but once in the loop I would expect everything to pass right ???

Thanks form the help

robtillaart:
when there is only the c typed in the monitor it is read by this line first

int inByte = Serial.read();

then VIPassing() is called

and the first thing it does is

SerialinByte = Serial.read();

:)while there is no byte in the buffer. This makes SerialInByte -1, which is not equal to 33
