Update of /cvsroot/src/sys/dev/isa
In directory netbsd1:/var/slash-tmp/cvs-serv29319

Modified Files:
        com.c 
Log Message:
If we get a RXRDY interrupt, but RXRDY is not set in the LSR, briefly set IER
to 0.  This fixes a condition where some UARTs send an infinite stream of
RXRDY interrupts.
