OK, I grabbed the 2.1 source using svn and compiled.  All went just

I only had a chance to try 3 serial drivers: Powercom, Fentonups and
Megatec.  All fail with different messages, but none works.  I tried
Fentonups because there is a reference to Powercom in it.  I could not
make dummy-ups work at all; it does not like my method, throwing syntax

My method (I've seen different instructions in this mailing list) was to
create /etc/ups/ups.conf containing:
	driver = fentonups
	port = /dev/ttyS0
	desc = "SmartLink"

and then run 'upsdrvctl start'.
If 'ls /var/state/ups' shows files, then 'upsdrvctl stop'.
'vi /etc/ups/ups.conf'.
Try again...

Carlos, if you have a static IP and if you promise not to shut down the
ups, I'd be happy to set up ssh access to the computer for you.  Please
be aware that the computer you'd connect has only an AMD K6 233 CPU so
it is SLOW.

Otherwise, I'll try each serial binary in drivers/.
