A short update on the RS-485 network project ...

I ordered up an assortment of RS-485 "hats" and USB serial ports
to play with.  I also have an Axxon LF1006KB PCIe card that will
go into the CPU server as the "gateway" for the 485 network.  It
should already work with the uartpci driver, but I'll have to extend
that to add support for the 485-specific card functions.  Fortunately
Axxon has been very forthcoming with documentation for the card,
so this should be pretty straight forward.

I decided to take this week off work so I could free up some cycles
to get myself orgainized enough to start on this ;-)  I need a week
just to dig out from under the mess that my apartment has become
during lockdown!  Mostly I need to (re-)construct a proper Plan 9
environment to base all of this on, so most of this week is dedicated
to building CPU and file servers, etc.  But just maybe, by the
weekend, I'll have a couple of Plan 9 devices chatting over the
RS-485 link.
