Do you think it an improvement? The man page for uplcom does not list pl2303ta, stopping at pl2303hx. The hx version is now EOL, superseded by the ta version. Prolific's migration guide at http://prolificusa.com/docs/2303/all/PL2303TA-Migration-Guide.pdf advises: "Note: Older driver versions are not compatible with PL2303TA chip for above 115200bps baud rates." I wonder if slowing the RPi2 consoles down would make the problems go away, at least until the driver is updated. It seems unlikely, given that the lockup is on the USB side.
