If you're using interrupts on either end then you shouldn't use SEROUT/SERIN as interrupts will upset the timing.
You should use the hardware HSEROUT/HSERIN routines, but then you will have to use...
I guess then, the sending device is interrupted by the USB routines while sending and as a consequence the transmission of RS-232 at that time is corrupted.
So I have a need to override a pushbutton (from ON to OFF) and came up with this concept; a solenoid piggyback on a pushbutton switch with a 3D printed cap held by a strand of wire.
