I think it's probably the right thing to do to hang up explicitly anyway though; otherwise quitting NM might leave the card in data-enabled state, even though no packets are getting transferred because PPP is down. (note this isn't a problem with 0.8 and modem-manager...) BTW, is the AT interface for TD-SCDMA any different than for normal GSM/UMTS cards? Are there PDF specifications for the AT commands you could point me to? Could you grab the output of "AT+CLAC" for me on your TD-SCDMA card? Thanks!
