A small lib for use with SDCC and a 8051 target for using the SIO in polled mode without disabling a running SIO IRQ. It is intended for use with the Tasking Monitor and a preconfigured SIO. The routines  have been tested with my development board. A Makefile for multiple file SDCC project include.
