TCP
9/12
Using RAW TCP Sockets
A raw TCP socket connection which can be initiated from the serial-Ethernet device or
from the remote host/server. This can either be on a point to point or shared basis where a
serial device can be shared amongst multiple devices. TCP sessions can be initiated
either from the TCP server application or from thePerle IOLAN serial-Ethernet adapter.
UDP
Using Raw UDP Sockets
For use with UDP based applications, Perle IOLANs can convert serial equipment data for
transport across UDP packets either on a point to point basis or shared across multiple
devices.
Console Server
10/12
Console Management
For access to remote console ports on routers, switches,etc, Perle IOLAN’s enable
administrators secure access to these RS232 ports via inband Reverse Telnet / SSH or
out of band with dial-up modems. Perle IOLAN models with integrated modems are
available.
COM/TTY
Connect Serial-based Applications with a COM/TTY Port Driver
Serial ports can be connected to network servers or workstations running Perle's TruePort
software operating as a virtual COM port. Sessions can be initiated either from the Perle
IOLAN or from TruePort.
Tunneling
Serial Tunneling between two Serial Devices
Serial Tunneling enables you to establish a link across Ethernet to a serial port on another
IOLAN. Both IOLAN serial ports must be configured for Serial Tunneling (typically one
serial port is configured as a Tunnel Server and the other serial port as a Tunnel Client).
Virtual Modem
11/12
Virtual Modem
Enables the serial-Ethernet adapter to simulate a modem connection. When connected to
the IOLAN and initiates a modem connection, the IOLAN starts up a TCP connection to
another IOLAN serial-Ethernet adapter configured with a Virtual Modem serial port or to a
host running a TCP application.
