Telnet Over Serial Port Ubuntu
I am working on an application which reads environmental instruments which have serial ports. The application requires a serial port to be present to talk to the device (i.e. /dev/ttyS0 ). In some instances the environmental devices will be 100's of yards away from the computer, so a serial cable becomes a liability. In these scenarios we would like to use a multi-port terminal server which serves up multiple serial connections via telnet.

I have a '3one data' brand serial-to ethernet converter, that plugs into a serial device at one end, and allows bidirectional communications with the device over an ethernet connection, like this: There is supposedly a way to set up a virtual serial port in Ubuntu, which maps to the IP and port of this device and allows transparent communication with the real serial device on the other end. Unfortunately there was no linux documentation accompanying this device, despite the fact that linux support was prominently advertised.
