Hi,

I'm trieng to copy files between an old DOS-PC and win10 via Laplink.

Low baudrates arre working but I allways get Warning: tried to activate hardware handshake
I've found the waring message in serialport.cpp

void CSerial::Write_MCR (Bit8u data) {
// WARNING: At the time setRTSDTR is called rts and dsr members are still wrong.

But I can't figure out why these waring is send to log and why hardware handshake is not working.

Second issue is Serial1: Errors: Framing 27, Parity 0, Overrun RX:0 (IF0:0), TX:0, Break 0

best regards
Frank
