Use ASCII

How best can you point in detail with the code

CodePudding user response:

Use first convert a string to a byte array of ASCII byte string, a serial port is sent the byte array, I didn't install mscomm, suggested a Cport serial interface control, easy to use

CodePudding user response:

SPCom works fine!
Than the MSComm that!

Converted to ASCII characters:
Var
S: a string;
BASCII: array [0.. 49] of byte;
I: integer;
The begin
S:='6820 aaaaaaaaaaaaaa1a039a4f003416';
For I:=1 to lenght (s) do
BASCII: [I - 1]=Char [I] (s);

Turns into ASCII characters with the word () function

On a post from you in light of the problem is that you put the string into a byte stream, the positive solution to the upstairs
