More Serial Ports/Terminal and UPS

Post by James O » Mon, 14 Feb 1994 12:08:40



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.

There are many serial boards that can be used with Linux
I have a Boca ioAT66 which provides 6 16550A ports with all handshake
signals present.  Other boards not always provide all signals when >4
ports are on the board!

Look for a board with only UARTS on it, no 'intelligent' board.  These
are not yet supported by Linux.

I would go for the STB 4COM since you already have 2 ports going.

each port can use one of eight IO addresses and all of them can share a
single interrupt.

4 ports, 16550 compat, works like a dream.

Can someone suggest a vender for serial boards? I've dug through all the
catalogs at work and home and only saw one board, a BOCA that needed to
use an interrupt for each port.

Our company (SW Technology) carries many communication boards,
including high speed IO boards and the intelligent boards. Some
of these are listed in a file on our anon. ftp site:
ftp.netcom.com, directory /pub/swt/info.

1. Configuring serial port for PowerChute UPS

Hi, I've got a Sparc20 server on which I'm trying to configure the
PowerChute UPS software.  The problem I'm having is that the software
needs to communicate with the UPC via a serial port, but the serial port
is being used by a terminal (the server has no graphics card).  

I assume that this is a frequently encountered situation, and I am
curious how other people deal with it?  Do you disconnect the terminal
and only use it when necessary?  Or is there a way to connect the UPS to
the AUX port on the terminal?  Or is there a second serial port on the
sparc20 that I don't know about.

Any comments/suggestions will be appreciated.
Regards,
