    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    But what if the serial cable is 'amplifying' the unloaded pin, as in a floating input, and it ends up causing garbage to try to get into the SERIN statement.

    How about adding a pullup or pulldown as appropriate?

    ok, I took out the pause, added the #, so the serin now looks like this...
    serin portc.3,t2400,10,mainloop,[#pcsig]
    it still locks up,
    i added a 4.7 pull down to rx, no luck
    pull up no luck
    serial cable still not even connected (just trying to get it to run first with serin command intact)
    will keep trying
    thanks
