How can I send Unicode characters (16 bit) with Serial port in Delphi 2010? -

-

i have problem in delphi 2010. send pc unicode (16 bits) characters printer serial port (com port). use tciacomport component in d2010.

for example:

ciacomport1.open := true; \\i open port data := #$0002 + unicodestring(Ж) + #$0003; ciacomport1.sendstr(parancs); //i send data device

if printer characterset ascii characters arrive, ciril character '?' on printer screen. if printer characterset unicode characters not arrive printer.

an unicode character represented in 2 bytes. how can decompose unicode character byte byte? example #$0002? , how can send strings byte byte comport? function?

under windows (check os how open , write comm ports), use following function write unicodestring comm port: bear in mind port have setup correctly, baud rate, number of bits, etc. see device manager => comm ports

function writetocommport(const sport:string; const soutput:unicodestring):boolean; var    retw:dword;    buff: pbyte;    lenbuff:integer;    fh:thandle; begin    result:=false;    lenbuff:=length(soutput)*2;    if lenbuff = 0 exit; // nothing write, empty string     fh:= windows.createfile(pchar(sport), generic_read or generic_write, 0, nil, open_existing, 0, 0);    if (fh <> windows.invalid_handle_value)    try       buff:=pbyte(@soutput[1]);       windows.writefile(fh, buff^, lenbuff, retw, nil);       result:= integer(retw) = lenbuff;          windows.closehandle(fh);    end; end;
