Udskrivning efter modtagelse af et bestemt tegn.

Og hvad er spørgsmålet ?

Ovenstående kode tester om første tegn i Buffer1 er '>' og kalder sendplc og
udskriver Temp1 hvis det er

problemet er at den skal sende til bufferen og først udskrive den når > tegnet er modtaget. Det som den gør her at den kun udskriver > tegnet.

Jeg tror at vi skal se lidt mere kode
