How to access the modem in QtMoko

dear neil,

thanks for your answer. the reason I wanted to try sending commands to the 
modem directly is that I have problems setting up my gprs connection with
qtmoko. Now I have found one site where
they state the AT-commands for manual modem configuration. So I wanted to
try those out.
Now I have found to the packages which is needed to be able to execute "cu" 
which is uucp. Now I can apparently connect to the modem with 
cu -l /dev/ttySAC0 as I get a connected statement printed on the screen after
having set the right permissions. Then the whole terminal freezes, but not
the phone. So I won't be able to send any AT commands. I guess this might be
be explained by your answer: there can be only one for modem access... On the
other hand I think that the openbmap logger and cellhunter allow to scan
your main cell and neighbour cells and allow you to make calls as well, whilst
they run (even though they might not do their scanning during the call).

Generally speaking I would like to 
a) turn the modem off completely if I want to do GPS tracking only to save
b) scan main and neighbour cells and still be able to receive calls to bring
   my little progress on gsm-location also to qtmoko (works kind of in shr)
c) try to send some at commands to see if I can do something to get my gprs
   working in qtmoko/shr

so if anyone has some hints/ideas, please let me know.

best regards
