Here is a draft of a news posting for VMS modem port information.
Look it over.  If you have any improvements to contribute, do so, or if you 
have any questions, let me know.   Note the offer to post progress
of the project.

Subject: Vax2000 serial communication port - VMS

We are designing multiprocessor DSP system to run off a VME 
backplane, with a VME133 board as the system controller.  For a 
user interface to the system, we are using a VAX2000 workstation
running VMS, and connecting to the VME through the serial modem 
line.  The VME133 serial port interface is a Z8530 chip, which 
follows standard RS232 protocol. If anyone has any experience using
the modem port as a serial communications line, we would appreciate 
some helpful hints.

Initial questions we have:

	Are there any drivers available for using the modem port
for communications such as this?

	Are there any system configuration issues?

	If we have to write our own driver, is there anything available
that might make the job easier, such as a similar driver that would need
modification only for this application, or a manual describing the
required information for writing driver?

	Thank you in advance.  If there is any interest in the problem,
we can post our progress on the project.
