[Nut-upsuser] APC SC 450 serial connection
support at plecavalier.com

I'm trying to connect my debian box to an apc smart-ups SC 450 with serial
port only. The debian box has a serial male port. I' got nut-server and
client installed put dumb as the driver.
driver = dumb
port = /dev/ttyS0
cable = 940-0024E
00:02: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A
I also bought a cable with a FTDI chip which Debian sees as ttyUSB0 but
that isn't working either.
All I ever get is Driver not connected.
