    the code txes to pc. i think interrupt is for sbuf

    sbuf sends to pc not comopiler

    It's not talking about you interrupting the build process!

    The concept of Imterrupts is absolutely basic to just about all computers - they go by the name of "IRQ" on PCs (short for "interrupt request")
