David Anderson 12ddbeb508 debugger: start of a debugging TUI for GARY
Uses the serial debug module and currently only works with
hardware/ulx3s, probably only on my specific machine where the
USB serial port is mapped _just so_. But it does work. Very WIP
unclean code, but checkpointing because it can hex view and hexedit
correctly.

David Anderson 8ab867d2d2 lib/UART: move from debugger, it's generic enough 2024-09-13 23:05:48 -07:00
David Anderson 379ebf0411 debugger/UART: implement a UART with RTS/CTS flow control
In practice the flow control is unusable on ULX3S dev boards because
the CTS line isn't hooked up (it's instead wired to JTAG_TDO, to enable
the USB<>UART chip to serve a dual purpose as a bitbanged JTAG programmer)

Still, support for flow control is nice, for the future. And the UART
itself also works regardless of flow control, which is of course nice.
