Netburner SBL2e ?

[Gargoreg]

I connected the UART pins from a PIC 16F1823 directly to the UART pins on the Netburner. Both are TTL so it's a direct connection. As the Netburner will connect to an IP address when the UART is openned, you'll need to have another networked computer listening on a dedicated port.
This computer would need to send the email. Unless you could connect the Netburner to a SMTP server and get the PIC to comunicate with the server and send the email.
In my system; my remote computer connected to the Netburner's UART via the network, this allows the remote computer to communicate with the PIC UART as if it was attached to the remote computer.
I would be happy to give you my code but I write in assembly. I only come to this forum to praise the Netburner SBL2e.
Another way is to use the general IO pins. You sensor sets a PIn and another computer on the network can monitor the Netburner's pin.
