DIM indata$, onechr as byte

open "C",#sport,115200,_noparity,_onestopbit,_eightbits,2000
handshake #sport,_none

rcvcnt=LOF((sport),1)// shows the number of bytes in the port

read #sport, indata; rcvcnt //This empties the port into indata:

onechr = indata[11] //  reads the 11th character:

But if you want to read a particular character from the buffer without 
clearing the buffer, I can't help...
