SOFTWARE UART LIBRARY
The mikroBasic PRO for AVR provides routines for implementing Software UART
communication. These routines are hardware independent and can be used with
any MCU. The Software UART Library provides easy communication with other
devices via the RS232 protocol.

Note: The Software UART library implements time-based activities, so interrupts
need to be disabled when using it.
