Almost all my friends in France have a old ISP modem router that their former ISP did not bother getting their hands back onto when they changed providers.
I would love to repurpose them. Where do I start with ?
- redfast00 4y agoTry to identify a serial port on the PCB, connect a serial adaptor to it (careful to get the pins and voltage right!) and take it from there (Edit: or google the PCB board markings, maybe somebody already did this)
- kjs3 4y agoFinding the JTAG port is also useful, combined with something like OpenOCD.
