I have experienced some problems using the select call in Xenix 386 V2.3.2.
It does not seems to detect when a pipe gets ready to been read from.  I also 
have trouble using select on a serial port.  When I do that the input
turns into garbage.  This does not occur when I use select on the
multiscreen ttys (tty01-tty12).  I am writing a communication
program allowing the use of Norwegian (special) characters (they all 
have values greater than 128), that resembles cu.  Instead of forking 
off two processes to read the keyboard and the serial line I am trying
to use the select call to detect when a character is ready from the 
keyboard or the serial port.  But when the select call screws up like 
this it isn't possible to use the select call.  If anyone have a
solution to this problem I would be glad to hear from you.

Please email answers, I will summarize.
