Minicom settings on v3.0?
I'm working on a program that sends AT commands to the modem (/dev/tty.debug), and I've recently upgraded my iPhone 3G from os 2.2.1 -> 3.0. However, Minicom just sits there when I open it up from SSH (using the same settings that I used on v2.2.1).
Accessing this device programmatically isn't working either. After moving my program out of the sandbox area, I'm able to open the debug tty device, but any subsequent calls that use the opened device block the process and don't return.
So, I have the following questions:
1). it seems obvious that the serial port settings changed from 2.2.1 to 3.0? (anyone know the new settings)
2). Is there an alternate method of sending AT commands other than opening up /dev/tty.debug, emulating a VT100 connection, and issuing read()/write() calls?
I'm really just trying to show the info that the FieldTest.app shows (LAC, Cell ID, RSSI) to get an idea of cell size/signal strength... There's obviously a mechanism for that app to access the info from the baseband.. presumably either an undocumented set of AT commands (LAC, Cell ID, RSSI are all from the 3GPP spec, however), or an API that directly gets network info from the baseband. Anyone know how the field test app gets its info?
