The classic terminal emulator is 'cu': http://www.airs.com/ian/uucp.html RedHat and Fedora have a package for it.
I rolled my own with special features to handle file transfers to mini-computers that can't turn off echo... There are other packages like minicom, kermit, etc, that support more advanced file transfer over serial lines. But the file transfer features are irrelevant to talking to a UPS. Serial communication can be quickly jury rigged in an apocalypse - unlike ethernet, USB, and other modern (and much faster) wire protocols. Keep such software archived. Note that even if computers no longer come with UARTs, you can still do serial communication with digital input/output and a timer interrupt. (I found 3 DI samples per bit time works reliably.) I have a real wyse60 CRT terminal if you are interested. :-) Once you connect to the serial port with your terminal emulator at the proper baud rate, it is like a shell prompt - except the UPS has only a few one letter commands. _______________________________________________ Nut-upsuser mailing list Nut-upsuser@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsuser
