You're right ! ... I talked to fast ;)

For specific commands (such as Z), we may just wait and ignore any
answers (as we did by the past).

still ignore the result of mge_command(... Z)

Fore sure :D 

 - see the
result of Marek's mention, i.e moving the double Z before the Si test.
For sure. I dig on my archives, and found a serial spy log taken on
Windows between PSP and ESV8.
 Z is send twice, then AX 1, then SI 1.

yep, with 500 ms inter-commands... I still have access to that code ;)
By the way, I worked a lot to make support of programmable outlets. By
now, it is not supported (even for recent UPS, working on usb-hid). I
may test and patch.

 @Ivo: could you send me your log file?

how do you want to proceed on the UTalk issue?
I can either provide a
(set of) patch(es), or few directions...

Let's wait Ivo's answer and
log files. Then, I'll try to fix it. Then we test it, and validate on
severals UPS. If OK, I'let you publish patch Arnaud. 

If I have some
time, I can work on programmable outlet, with limited support to onboard
one (no external outlet plugged in daisy chain).
