Recently I was fooling around with the serial device and found that there
was almost no use for sharing the serial device.  Is it just me, or do others
have problems when they try it too?

I open 2 ports and 2 devices.  One to read from and one to write to.  Every-
thing works fine.  I runback the program and then runback another one.  I
loose every other character.  One program gets one character and the other
the next. 

When I quit the program (close both devices and both ports), the TR (terminal
ready) light on my modem goes off, meaning the serial device was closed.  I
don't think that should happen since I should have 4 serial devices open, and
closing 2 of them shouldn't close all 4.

Am I totally missing the point?  Should I give some example code?  Is there
a book on programming the serial device?  The 1.3RKM:Libs&Devs doesn't say
too much on sharing and I don't have the autodocs or hardware manuals.

Any help would be greatly appreciated...

Thanks
