hello,
disclaimer: David Coppa told me to post this to tech@ so this is not a
case of cross posting.
bought a ZTE MF112 today for my girlfriends ms win notebook. Took the
chance to test it on OpenBSD.
Without the patches below the thingy attaches as umsm for a second,
detaches and re-attaches as umass.
After patching it attaches as umsm0, umsm1, umsm2, umsm3 and ucom0,
ucom1, ucom2.
ucom2 is the one you would want to use with pppd.
I inspected the modem log on ms win to find out what AT commands are
used by the proprietary software, here we go:
TIMEOUT 5
ECHO ON
ABORT "BUSY"
ABORT "ERROR"
ABORT "NO CARRIER"
ABORT "VOICE"
ABORT "NO DIALTONE"
'' AT
OK ATV1
OK ATE1
OK AT&F&D2&C1S0=0
OK ATS7=60S30=0
OK ATS0=0
'' AT
OK ATV1
OK ATE1
OK AT&F&D2&C1S0=0
OK ATS7=60S30=0
# that's what it realy does: OK ATDT*###
# but does not work for me on OpenBSD, so use usual:
OK ATDT*99#
CONNECT ""
Do not ask me what the unusual ones of these commands do; all I can say
is that I got a working internet link and minimal testing showed:
(I got excellent reception here.)
- got max speeds around 250KB/s
- speed changed often and dropped down to as little as 1,5KB/s
- sometimes it stayed there, sometimes it increased again.
I am going to stick with my "Sierra Wireless, AC850, 3G Network
Adapter". Gives me "only" about 80KB/s but that reliably.
btw, what is the right list for such patches?
bye,
Marcus
