RE: [ECOS] Example ISR,DSR for ARM AEB-1

[Gary Thomas <gthomas at redhat dot com>]

Look at the AEB serial device driver.  It sets up the ISR/DSR for
exactly one serial port.
  .../io/serial/VERSION/src/arm/aeb_serial.c

BTW - the point of the whole interrupt scheme is that your code 
need not manage any decoding, masking, etc, directly.  This is
all done using either the HAL macros, or more usefully, the KAPI
interface functions (like in the serial device drivers).
