[Nut-upsuser] MGE-UTALK regression since nut-server-2.2.2

[Sébastien Lefevre]

Hi all !

I have communication issues between my station and my old Pulsar EX10 UPS,
(U-Talk) connected by RS232, when using v2.4.1 of nut-server.

I tried to come back to version 2.2.2 and then, communication start and is
operational.

Maybe it's linked to bug 498655, but i haven't seen any answer ?

Here are results of my tests (differences are in *red*):

Does anyone know about it ?
I think it's a software bug but I'm waiting for yours opinions.

Thanks !
