[PATCH] for ModemManager to add (partial) support for ZTE MF192

[Dmitry Morozhnikov <dmiceman mail ru>]

Hello All.

Not sure if this is a right place to post a patch. Actually a simple 
one, what drop more than add :-)

Anyway..

ZTE MF192 does not respond properly to the AT%IPDPACT command:

--> 'AT%IPDPCFG=1,0,1,"mts","mts"<CR>'
<-- '<CR><LF>OK<CR><LF>'
--> 'AT%IPDPACT=1,0<CR>'
<-- '<CR><LF>ERROR<CR><LF>'
Got failure code 100: Unknown error
--> 'AT%IPDPACT=1,1<CR>'
<-- '<CR><LF>ERROR<CR><LF>'
Got failure code 100: Unknown error

Thus, it can't work with icera command set. However, it partially work
with generic command set:

--> 'ATD*99***1#<CR>'
<-- '<CR><LF>CONNECT 7200000<CR><LF>'

but:

--> 'AT+ZPAS?<CR>'
<-- '<CR><LF>ERROR<CR><LF>'

and more importantly:

--> 'AT+ZSNT=1,0,0<CR>'
<-- '<CR><LF>ERROR<CR><LF>'

Can, please, someone point me to the way to avoid this incompatibilities?

Anyway, I think it is better than nothing:
