I don't know what it would be specifically, but having dealt with similar problems on other Unix systems, it's proably the case that zsh uses a particular tty mode that isn't correctly supported by the serial console driver, either due to a bug in the driver or due to a conflict with some other feature enabled on the console port. The next step to take would be to run "stty -all" under /bin/bash and under /bin/zsh on a telnet session, and compare the outputs.
