And I think somthing else where P9 differed from UNIX was dealing with OOB (control) information (*i.e.* ioctl(2) was a terrible misstake). Dennis and Ken created ioctl(2) with v7 as a generalization of stty/gtty from the TTY handler. At the time, it seemed like a reasonable way to handle those 'small things that need to be tweeked - like baud rate or canonicalization; but ioctl(2) quickly got abused as the universal end-around, and those things caused also sorts of issues (also being a binary interface only made it worse, although on the PDP-11 it made sense for size reasons). Creating a seperate interface from the 'file' to orchestrate/control the I/O and controlling that as a set of strings not binaries, seems like a more sane idea. ᐧ
