Sample program:
10 OPEN COM1: AS #1
20 OPEN DATAFILE AS #2
30 PRINT #1, A
40 INPUT #1, DATA$
50 IF DATA$ = EOF THEN END
60 PRINT #2, DATA$
70 GO TO 30
80 END
The program transmits A as the line request character and checks each input line to see if it
is the end-of-file character string. The FieldBook responds with a line of data followed by the
end-of-line sequence.
