how to get spin to check string input from serial terminal

Bulslayer85

how do i get spin code to check text i input in the serial terminal and do something or rather post a response based on what text i input.

Example: i type "how are you?" and robot responds with "I am fine" but only if i type that exact phrase.

There are some objects in the Propeller Object Exchange that extend FullDuplexSerial or FullDuplexSerial4Port to include some input routines. One of them (StrIn) copies serial characters into an internal buffer until a delimiter (usually Return) is processed, then it returns the address of this internal buffer. To compare to an exact phrase, you'd do something like

' The input routine has returned the address in Addr.
if strcomp(Addr,string("how are you?"))   ' Check for exact equality
   ' Do something if there's a match

ok, i found that the parallax serial terminal object has a StrIn function with (stringptr) but when i try to call that function in my code it compiles and says that it expects an expression term in the (). totally confused cause the actual PST code file compiles fine i just cant seem to refer to that function in a different code file.

Robotics class teacher helped me out so nvm, turns out i was supposed to assign a var to where stringptr was. so oops oh well. all works fine now
