Right now NM doesn't call disconnect at all, AFAIK. It just calls
Enable(false). We assume that also cleans up the connection and
disables the modem, since disabling the modem implies the connection is
torn down. Is that not working?
BTW, how do you handle breaking into the ongoing PPP session on a 1-port
modem and hanging up the connection? +++ATH? Or AT &D1, setting the
serial port's DTR to off and then ATH?
