Enable Serial2 on the 2 series

[clarkbremer]

Using ATtiny824, and naively attempted to set up Serial2 the same way I would on an old "mega" board. What's the trick for using the second uart on the "2" series?

There are no tinyavr parts with a Serial2. You want Serial1. There's Serial and Serial1. Take care if using the .swap() method. There are 2 serial ports each pf which can be on 1 of 2 pairs of pins, but serial default pinscand serial1 alt pins are the same pins

And of course that works perfectly. Thanks, Spence. I was thinking Serial == Serial1. The ESP32 has 3 uarts, which is why that worked for me in the past.

Yup. On dxcore but I don't think here, Serial is just a #define and the actual object is called Serial0, so that one could create a variant file wher default port wasn't the zeroth one. With only two ports sharing 3 pairs of pins one of which is only present on larger parts it seemed silly.
