Does anybody out there know anything about the black art of sockets and RPC on sun machines? To be more precise: I am trying to exapnd the number of tty lines controlled by a diskless sun workstation. The workstation has only got 2 serial ports and I am working on a project requiring direct control of upto 5 serial devices. Rather than spend a lot of money on a terminal concentrator to attach to the ethernet, I was wondering if there was any straightforward way of using sockets and a suitable daemon to utilise spare tty lines on another machine. The hardware used is 4 3/60M diskless stations attached to a 3/280S file-server all running SUNOS 3.5. Ideally, I would like to use 5 tty lines on the server, leaving the workstation(s) to do the fancy graphics. I would like the workstation to view the lines as files (sockets) thus relieving the programmers involved from learning about RPC. Thanx in advance.
