RS-232 Operation Using Quick BASIC

The following example shows how to send command instruction and receive

data responses over the RS-232 interface using Quick BASIC.

The program example is set up on "COM1".

CLS

E$ = "A"

ST1:

CLOSE #1

OPEN "COM1:1200,E,7,1,DS,RS" FOR OUTPUT AS #1

PRINT #1, E$;

CLOSE #1

OPEN "COM1:1200,E,7,1,DS,RS" FOR RANDOM AS #1

ST2:

INPUT #1, A$

B$ = MID$(A$, 2, 6)

DEC = 0

F$ = "0123456789ABCDEF"

N = 6

FOR I = 0 TO 5

C$ = MID$(B$, N, 1)

N = N - 1

D = INSTR(F$, C$) - 1

DEC = DEC + (16 ^ I) * D

DEC = DEC / 1000

C$ = MID$(A$, 1, 1)

1 2 ... 7 8 9 10 11 12 13 14 15 16 17 18 19 20
