Source-Level Debug with Algorithmics' gdb

To use the debug Monitor with Algorithmic's gdb, you will need two serial ports. One serial port (connected to the Monitor's tty0) will be used as the console. This port is used to issue the command 'debug'. It is also the port where program I/O will appear. The second port is used for gdb to communicate with the Monitor's tty1. It is also used to download the program prior to switching to 'debug' mode.
