Trying to flash a DM16L just drops me to "SERIAL CONSOLE"

[Dave Britten]

This is rather odd. I've got a 41L and a 16L. Both were running firmware 22 as of this morning, and I noticed 23 is out now. I backed up, updated, and restored the 41L with no problems.

I backed up the 16L, and when I press the RESET button to try to update it, I just get the boot info, and it drops into "SERIAL CONSOLE". I ran the keyboard test to verify there are no stuck keys, and I've flashed it with new firmwares in the past. Anybody seen this before? I'm flashing from a Windows 10 desktop.

EDIT: Restarting the computer seemed to get it going for some reason. No idea why. Might be that there's some emulated serial control line (DTR? RTS?) in the USB-to-serial chip and associated driver that was "stuck" or something. So if you run into this issue, try rebooting, I guess.
