I believe that this is an unclaimed interrupt error, but I can't find 
anything to support this.  The closest thing I can refer you to is the
AApple ProDOS 8Technical reference manual, where, under the heading
"system failures," it lists an unclaimed interrupt as a cause.

This is also supported by the fact that your serial card on the modem is
*probably* generating interrupts for the modem program (although I have
no idea how Kermit in particular works).
