What are the correct settings on an RPI3 to watch the serial console using
a pl2303TA usb-serial cable? In this case, the monitoring window is on the
same RPI3 as the serial console being monitored.

At this point /boot/cmdline.txt contains

dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=/dev/mmcblk0p2
roo
tfstype=ext4 elevator=deadline fsck.repair=yes rootwait

The monitoring window is opened with
screen /dev/ttyUSB0 115200

There appears to be a login prompt, but it's mixed with a blizzard of tabs,
spaces and carriage returns, as if a local echo of some sort is causing
spurious feedback. The blizzard occurs regardless of whether any input is
typed on the screen session. It starts slowly, then speeds up. It doesn't
seem possible to enter a login and password successfully.

Thanks for reading, and any guidance!
