[Coco] Serial stuff. 6551 ACIA. LAN/Wifi adapters. Drivewire

Thanks.  Saw that one.  I'm not sure how well it would be suited for the CoCo especially under OS9/Nitros9 as it contained prebuilt utilities and not generic net protocols.

But that led me to the ESP8266(.net) which appears to provide many different protocols over serial to WiFi including an implementation of SLIP.

You apparently are not on Facebook.

I am not sure if what you want is the same but something was posted to Facebook in the last few days.

Opps, a Evil Bay item.

Software is just that, "soft" and can be changed.

The 6551 is not hard, I wrote a driver to read a serial keyboard for Flex. Try getting a hand built computer up and running with two (2) defective floppy drives. Been there, done that. New drives and Flex came up the first time.
