Wait for a string on a serial port

[flotulopex]

MAIN:
SERIN2 DataIn,BdRate,[WAIT("Identifier"),Switch]
IF Switch = $31 THEN TX_ON = 1
IF Switch = $30 THEN TX_ON = 0
GOTO MAIN
END

...or in serialtool send Identifier#1...

Thanks Richard, it works well expecting HEX values ($30 and $31) but it will not work with Identifier#1.
