The PIC ports with HSEROUT and HSERIN are already taken. Using a baud rate of 9600 instead of 19200 made a difference. It is now working fine. The USB Darrel's interrupt takes micro seconds to...
The design is based on a classic switch (On/Off) but if I understand correctly, in special cases, the push button should be in a specific state and user is not allowed to change that.
not sure if I am understanding what you need, but if you need an indicator that the mechanism is in one position or another then a hall effect switch is just a simple 'proximity sensor'..... when the...
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.

Re: SERIN2 Receiving Wrong Data
I think it can be right since Serout/Serout2 happens in a async rate. USB is fast but in any case the soft Serial is interrupted randomly.
