The default configuration on the SD card image is to log you in as 'glenda'
and start a shell session using the screen and keyboard. In this mode it
won't be prompting for commands on the serial console. Not helpful for
a pi zero with no screen or network connection.

If you edit cmdline.txt to remove the 'user=glenda' definition, you should
get a 'user[none]:' prompt when you boot. If you supply any username other
than 'glenda', it should give you a shell session on the serial console.

You'll find the environment with only a serial console to be pretty limited.
Plan 9 is designed either to be used as a "terminal" (with screen and keyboard)
or a "cpu" server (accessed from the network). For the pi zero, I like to
use a micro-usb hub with built-in ethernet adapter, like this one

In cmdline.txt, the (single) command line should include the definition
  console='0 b115200'

In config.txt, the stanza for the pi zero (or the [all] stanza to be
completely sure) should include the line
  core_freq=250

Then you should be able to connect at 115200 baud.
