 I would assume then that Xenia is similar.  I can write to the port using

 DosWrite and it seems happy ...  :)

 Okie.  I assume that after I fiddle with the settings, I should probably

 set them back the way I got them (when my proggie exits)?  Also, should

 I worry with setting up a thread to handle the I/O or just let OS/2 buffer

 it.  I've been going round and round with that and I can't see much

 benefit in buffering it myself.
