It's the Unicode character used to identify the device driver within a
kernel,
and are part of the device driver's Dev value. Only a few have any sort of
global
significance, and even that's probably a mistake.

cat /dev/drivers
for the map currently in use. /sys/src/9/port/master tries to keep track of
them,
but as you'll see some characters are used for several devices (not in use
simultaneously in the same kernel)
