Okay, I've got to add a terminal and UPS to my machine at home, and I don't
have the available serial ports (currently have two: com1: 16450 and mouse,
com2: 16550AFN and modem). My questions is what do people recommend in
terms of hardware to add a couple of more serial ports to a PC running
Linux (preferably 16550AFN compatible).
As can also be surmised from the above, has anyone set up a Linux machine
to automatically shutdown upon a signal from a UPS (with an RS-232 connection
of course). If so, could you give me any pointers?
Any help would be appreciated.
