I thought that this 'immaturity' was always present with SysV UNIX:es,
i.e. the only way to program the speed/other attributes for a non-respawn
port was to write a small program that opens the port, ioctls the new
values, and keeps the port open until the doomsday of the running system.

It's always a fun game trying to find out the default port values of the 
manifacturer's UNIX system. Sometimes they even document them.

Kent
