Hi there, I have GSM modem connected to ttySAC0 to micro 2440 and i would like to connect to the board using gprs connectivity thru serial port could any one guide?
micro 2440 internet thru ttySAC0
ttySAC0 is used by the boot loader, kernel and system for remote console. If you really want to use it you have to disable it. In this forum are several threads for doing this. Search e.g. for 'console' or 'ttySAC0'. Better is to use the FriendlyArm's TTL to RS232 converter for less than 10$ and connect it to CON2 or CON3 TTL output for ttySAC1 and ttySAC2. Good luck!
Thank you i already changed debug port to ttySAC2 using supervivi console and i am able to communicate with gsm modem using ttySAC0 Could you tell how to start ppp configuration i am using qtopia i not able to fine any ppp config files in etc folder
