Thanks for all your help, guys.

I have already manually updated the modem firmware to
1.2.2 ( c3600-2600-analog-fw.1.2.2.bin ), and the
log I originally posted was running with that firmware.

Are there some additional fixes in 12.2(10a) or 12.1(x)
beyond the firmware upgrade?

I have just spent the last couple of days trying pretty
much every possible combination of S-Registers at both
ends, and I will try pretty much anything at this point!

Thanks again

Best Regards,
Simon Hailstone
