Description j. alan eldridge 2001-06-13 01:02:18 UTC 
Description of Problem:

The genericups driver app is for "Stupid" UPSs that use "simple 
signalling". They don't transmit data, they just raise/lower control 
signals.

Opening the file (e.g., ttyS1) in blocking mode will block (and fail with 
a timeout) because the right signals aren't present.

The attached patch is against 0.45.0 but should work for 0.44.x as well.

The new nut-0.45-1 in rawhide has this patch. Thanks
