18668	Problem with sharing serial port after upgrade from 5.2.28 to 6.0.X	stagadet		"When I try to use a shared COM port (host device) on a guest running DOS 6.22 (using a legacy software for PLCs), on VirtualBox 6.0.8 (and also 6.0.6) I get errors like:
Serial#0: Failed to change parameters to 2400,NONE,5,1 -> VERR_INVALID_PARAMETER
and the software cannot communicate.

Everything works fine if I use VirtualBox 5.2.28 instead, with the same virtual machine.

The full log is attached."	defect	new	uart	VirtualBox 6.0.8		Serial		other	Windows
