Add code into the KeyPress event. A lot of keyboard wedge style scanners (barcode and CC) force a carriage return at the end of the string. You can intercept both the ESC or CR:
IF nKeyCode = 27 && ESC
ENDIF

IF nKeyCode = 13 && ESC
ENDIF
If the reader terminates with another character as Tracy mentioned, you can capture it here as well.
