Passing Specific Binary Characters in QTcpSocket.

[marcel]

That is because you write unicode characters to the data stream.
What you need is to write ascii characters:

QString s = "text";
QByteArray b = s.toAscii();
const char* ascii = b.constData();
out << int(0x02) << ascii;

QString s = "text";
QByteArray b = s.toAscii();
const char* ascii = b.constData();
out << int(0x02) << ascii;

To copy to clipboard, switch view to plain text mode
