Qt C++ signed unsigned mismatch

Well here's a nasty one (I think) Sending bytes over a line is usually an UNSIGNED matter. I have a device that sends unsigned bytes ( a byte should be unsigned ) over a line using a custom protocol, this cannot be changed !

And I wanted to use Qt to make a nice tool to read it all out. However...
some moron decided that a byte in Qt is SIGNED (QByteArray) and there is no way to make QSerialPort to receive in an unsigned container, nor can QByteArray be set to unsigned

Any suggestions ?

Perhaps one day we will find that the human factor is more complicated than space and time (Jean luc Picard)

signed and unsigned bytes are the same. It's only how they are interpreted. Just cast your ubyte stream to a byte stream, and then cast it back once it's received.

King Piccolo will make it so Then I could just flip it with some sweet, sweet matrix math. In either case, I’ll ride this wagon until the wheels fall off. Thanks to those that keep it running
