[Yevgeny Kosarzhevsky]

Hi,

I get a trouble using nut with PowerMan Back Pro N 1400 Plus

~# /lib/nut/megatec -DDDDD -a pman
Network UPS Tools - Megatec protocol driver 1.6 (2.4.1)
send_to_all: SETINFO driver.parameter.port "/dev/ttyS0"

4 out of 5 detection attempts failed (minimum failures: 2).
The UPS is supported, but the connection is too unreliable. Try checking
the cable for defects.


I have tried it on win xp with WinStar Pro and it works just fine. The
cable and UPS are new.

Any advice?
