In the case above we can go into RomBug by typing break and placing
a break at the ISR.
$ break
RomBug: b 1fed47
RomBug: g
and then pinging a machine on the network.
$ ping 182.52.109.13
(using the actual address of another machine on the network, rather
than the one shown here)
If interrupts are running you should be presented a Rombug prompt at
the breakpoint address. You can type g to see if you get another
interrupt or k to kill the breakpoint.
Port Address Conflict
It is also possible that the port address used for this card is used by
another device in the system. If this is the case the OS-9 command
netstat -in will not show the card as available.
The following netstat example shows a working network card
configured with IP address 12.52.109.25 and MAC address of
00.00.C0.91.4F.96.
