So this "auxiliary" is essentially synonymous with "peripheral"
or "serial peripheral".

Interesting, thanks.
According to Wikipedia, the PS/2 connection was designed in 1987
and the first release of the Linux kernel was in 1991. Therefore
"/dev/psaux" could have appeared in Unix before it appeared in
Linux. Whether the first appearance was in Unix or Linux, I would
have expected the name to be /dev/ps2 rather than /dev/psaux.
But stranger things have happened.
Thanks for the insight, ... Peter E.
