Very curious what that would represent, to a layman.

Seems it's seeking to the the first ($1) argument in /dev/port file and writing in stuff from the second argument ($2) with some hex/decimal magic. It's pretty hacky, but if it works, it works.

Seek operation may be working like "function selection" on that specific device driver. The hex encoding of the seek offset gave me such vibes.
