Has  anyone tested the following configuration?  I have a  system
running SCO Xenix 2.3.2, and would like to be able to run a Texas
Instruments  TI-810  printer, with a standard AT serial port.   I
have  tried  to configure various RS-232 cables and have  had  no
luck, though I have on an Altos system.  On the AT serial port, I
am using the 9 pin serial port.

I  am  having  a  flow-control problem.   My  understanding  from
reading  the  TI-810 manual, that the printer only supports  DTR,
and will not support Xon/Xoff.

My configuration is as follows:

       System          Printer     System         Printer
        9pin            25pin       9pin           25pin

- cable     2----------2                2----------2
            3----------3                3----------3
            5----------7                5----------7
            6----------20               6----------11
                   |---6                        |--6
                   |---8                        |--8
                   |---9                        |--9

If  someone  is  able  to  assist me,  I  would  appreciate  your
technical information.
