Historical setup means my UAMPORT needs to be set to 3660. I have flashed a new Picostation M2 with the latest firmware, but am unable to get the UAMPORT changed (from stock 3990). I have tried all the usual tricks, host.conf, config, hs.conf, but they ALL get overwritten on reboot. So I thought I would re-write the source file in usr/etc/chilli but they are all read-only.
If I had any hair left I would be pulilng it out ;-) anyone experienced same problem? Know a work-around or solution?
