SLIP router mode
17.1.2 Application example
Connecting two IP networks over serial cable
In SLIP router mode paired use of two Com-Servers allows two
IP/Ethernet networks to be connected over a serial RS232/422
cable. The prerequisite is that the two networks must belong to
different IP networks.
The gateway in the TCP/IP stacks of the computer must under
some conditions be configured to the IP address of the
respective Com-Server. If there are additional routers in the
network and these are capable of RIP protocol (

rotocol), the routing will work without explicit
configuration of the gateway address.
The serial transmission parameters for both Com-Servers must
be identical. Only hardware handshake may be used for flow
control. The use of software handshake is not possible due to
the
Xon
and
Xoff
characters which the Com-Servers process.

The maximum serial transmission speed is 230.400
baud. Transmission of the entire Ethernet-side
bandwidth is not possible.
The following sketch shows a sample configuration for paired
use of Com-Servers as SLIP router:
