FOR Your Information

This is second hand information from an internal Sun email
in response to a question on how to connect multiple serial 
devices to a machine such as a 3/60.

Serial Port Multiplexor For Sun Workstations
--------------------------------------------
(from another Sun employee ...)

	The fellow I spoke with at the Sun Expo is Mark Baker.
	He's the Vice-President of Vector.  Tell him Todd sent
	you!!!   :^)   His # is 602-741-0120.

	Mark said the VPX-127 sells for $1,495. 
	Here's the information I have.  It came from
	Vector's glossy....

"Vector Technologies	VPX-127 Multiplexer"
--------------------------------------------------------------------------------

Function Description:

The VPX-127 multiplexer connects up to seven serial devices to each
port on a Sun workstation.  This allows users of Sun workstations to
expand their current Sun configurations to add on peripheral devices.
Standard UNIX baud rates of 50 to 38,400 baud can be specified for each
port.  Each port fully supports XON/XOFF flow control.

The multiplexer firmware automatically gathers characters together
until 50 mSecs expires between characters or a packet is filled.  Using
a fast auto-repeat key on terminals does not send data until the
auto-repeat key is unpressed, or the multiplexer fills a packet.  Baud
rates, data packet sizes and flow control can be set for each
individual port.

Physical Description:

The VPX-127 multiplexer consists of two modules:  a control unit
consisting of one printed circuit board with eight DB20/RS-232
connectors and a power connector, and one power supply unit.  It
receives all configuration information, including the port-0 line
speed, from the Multiplexer daemon on the host.

Standad Features:

The VPX-127 multiplexer allows you to:

1) Attach up to 7 different devices to each port of
   the Sun workstation, for a total of 14 devices.
   [on a 2 serial port system, using two VPX-127's ---todd]

2) Define different baud rates for each port.

3) Define the baud rate between the Sun workstation
   and the VPX-127.

4) Define the size of data packets exchanged between the
   Sun workstation and the VPX-127.

5) Enable flow control using XON/XOFF for attached devices.

6) Connect dial-in/dial-out modems.

The VPX-127 comes with software to be loaded and executed
on the host Sun workstation.  This software provides
automatic device configuration which should satisfy most
requirements,  However, should the need arise to change
the default device assignments, the software allows
such modification.
