hello,

I'm having trouble communicating with RS232,

RS232 receiving uses interrupts (serial assistant sends once for 90ms), RS232 sending uses cycles (100ms), and now my sending is constantly interrupted by receiving interrupts. What can I do to prevent this from happening?

Apparently you need to clear particular interrupt flag in the interrupt service routine.

Pay attention to following bulletin, section 3.2:
