Configuration
4-19
4.1.4 Configuring via the RS 232 interface
The router is connected to a PC via the RS 232 interface "Console"
using a null-modem cable. The RS232 protocol is used directly so that
no IP communication is possible. The difference to configuration using a
zero-modem cable connected to the external modem connection is that
no full PPP connection is created; the router cannot be addressed from
the SSH or using a web browser.
The use of the RS 232 interface provides expanded diagnosis options
through direct output of all screen contents to the serial CONSOLE
output of the router, which is especially advantageous for the
configuring and maintenance of the router itself. Access to the
underlying network, however, is not possible.
It is also possible, however, to reload the original default settings if the
router is configured not correctly if you press the ENTER key when
prompted to do so during booting.
