First of all, I would like to thank every one who responded to my questions
about my voice synthesizer working with Unix.  I have just about decided to
get Xenix 386.  However, I would like to ask a few more questions before I
shell out the bucks.
I will need 4 serial ports.
com1 xt acting as a voice terminal.
com2 modem
com3 TNC; amateur radio rtty device
com4 Braille printer
Now, under MS-dos, I can share an IRQ line between serial ports as long as
I am not using two ports on the same line.  I suspect that Xenix wouldn't
like this very much.  So, I have looked into which IRQ lines are used for
what purpose.  My multiio card will allow me to use IRQ 2, 3, 4 and 5 for
serial ports.  This means I can use IRQ 2 and IRQ 5 for com3 and com4
respectively?  I can find no use for IRQ 2 and I know IRQ 5 is used for the
lpt2 port.  If I set up my hardware like this, what will Xenix think about
it? What will I need to do to let Xenix know what I did?  I would rather
not buy a multi-port card.  How do these cards generally work?  What will
happen to lpt2?
Also, does Xenix allow for vertual screens over terminal ports?  Will I
have the ability to switch between two or more processes from a serial
line?  I would like to be able to have more than one task active without
putting the extra tasks in batch mode.
How much of the docs is not provided with the man pages?

Any responses are quite welcome.  Thanks beforehand and maybe afterhand.
