SOFTWARE UART LIBRARY
The mikroC PRO for AVR provides routines for implementing Software UART com-
munication. 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.
