Changes

Many of the computers installed in the EHL do not have video output (because they're not intended for desktop applications). Most of these have a serial port; in many cases, the this is a virtual serial port can be which is accessed using the ICMP SOL (Serial-over-LAN) protocol on the network. Since this is not a TCP/IP protocol, the client must run somewhere on the LAN.

For systems that do not have a woring working ICMP engine, the EHL is equipped with a [[Cyclades Terminal Server]] for which provides remote accessto 32 serial ports. A remote user can connect to a selected port to monitor and control the connected system.
