Re: Bug#1115582: bootterm package fails on ppc64le

Hello Faidon,

  I've looked into it further and confirmed thatt he support for 
arbitrary baud rates via <termios.h> was introduced in *glibc 2.42*.
However, most current Debian environments (including stable and testing) 
are still using glibc versions *< *2.42, so the new support is not yet 
available there.

Given this, we’d still need to rely on the <termbits.h>. But once Debian 
moves to glibc 2.42, we can definitely consider simplifying the code by 
switching to the standard <termios.h> API conditionally.
