Good day,
I am using a PIC18F46K22 with two uarts. I have writte a small program which uses RS232 Channel 1 and works fine. When I change to RS232 Channel 2, it does not work? What can be the faillure? Do I have to change anything else?

Hi Beertree,
Channel2 is not being set up at all when it should be.
This would also have an effect on channel 1 stopping it from working as well.
So it looks like its a bug.
I will move topic to the bugs selection for Matrix staff to look at, for an official fix

I believe I have tracked down the cause of the issue.
There is a bug within PIC_CAL_UART.c
For an unofficial fix, can you replace PIC_CAL_UART.c within:
C:\Program Files (x86)\Flowcode 6\CAL\PIC if 64 bit windows
or
C:\Program Files\Flowcode 6\CAL\PIC if 32 bit windows
If flowcode is already running, best to reload flowchart after fix.
Can you let us know if fix works for you please.
