If I run it after a clean boot (with my current workaround to bring up
ctc0 [1] disabled), I get:

When using a real CTC, that is a wire cable between two separate
computers, (I haven't seen one of those in years either but they do
really exist) it is necessary to reverse the order on one. One machine
read=0A00 write=0A01 the other read=0A01 write=0A00. One machine has to
read what the other

Have we seen this in practice?
Because of the way the CTC driver is structured, one address is input
and one is output if you're speaking IP over it. It's not like using
CTC for RSCS where each address is bidirectional. So if only one of the
pair is there, I'd say that it's broken and you s

The ctc module is loaded. I have it in /etc/modules.
A manual 'hwup ccw 0.0.0a00' does indeed do the trick.
The problem seems to be that loading the ctc module does not trigger the
