You will get multiple /dev/cuaUX devices (4 in this case I believe) and you need to pick /dev/cuaU0. Start ppp with your usual entry and before typing dial you set the device to set device /dev/cuaU0 Don't forget to set the baud rate to 115200 or higher to set buffering correctly in the TTY layer. Oh no, that still needs fixing in the ucom driver. You will get lots of warnings. Increase 256 to 1024 in the following line: #define U3GBUFSZ 256 The problem here is that ucom doesn't properly initialise the tty struct. Setting this value isn't the proper way of doing this but it works. With screen /dev/cuaU2 and then typing in AT+CSQ you can view signal strength. Depending on the device the following commands you can try (while on the move): AT+CREG=1 GSM connection status AT+CGREG=1 GPRS connection status AT+CREG=2 GSM connection status including mast IDs AT+CGREG=2 GPRS connection status including mast IDs AT_OSSYS=1 Async selected system reporting (Option) AT_OSQI=1 Async Signal Quality Reporting (Option) Thanks for testing. Cheers, Nick
