Provision networked serial ports for roughing system

PFS will have two independent roughing stations, each controlled by an instance of ics_roughActor. From the software point of view, each station consists of a roughing pump and a vacuum gauge, and needs access to them. Specifically, for each station we need two terminal server ports:

• for the gauge: 2-wire RS-485, 9600-N-8-1 baud
• for the pump: RS-232, 9600-N-8-1

Both should be configured as raw TCP connections (no telnet, no Realcom, etc). The terminal server must be on the PFS network.

The actors will need the hostname and port numbers. This is required for SM1.
