MULTIPORT SERIAL CARDS FOR THE SUN386i

Comtrol, Digiboard and Harris-Lanier have working Unix drivers for the
Sun386i SunOS 4.0.1.  These boards allow for the connection of terminals,
modems, serial printers, data collection devices and plotters to the Sun386i.
ECD does not support these cards but has verified that the drivers do load
and a number of terminals were able to logon.  The distributors of these
products provide a variety of support programs and guarantees.  Reference
sites may be available from the distributors.  These boards also have not
been tested as DOS devices although this support may become available in
future releases.

	Product: Hostess 550
	   
	   The Hostess 550 is a multiuser board that provides 4 or 8 serial 
	   ports for the Sun386i.  The Hostess 550 buffers data to be
	   transmitted, reducing the number of interrupts to be processed.  

	   Technical specifications:
	     16 byte transmit and receive FIFO
	     4 or 8 port versions available
	     16550 UARTs
	     each port software controllable
	     full modem control
	     switch selectable hardware interrupts
	     multiple cards supported
	     supports 50 - 115.2 k baud rates
	     A Sun386i OS4.0.1 loadable device driver is available.

	Product: ULTRA 186
	   
	   The Ultra 186 is an intelligent multiuser board that provides
	   serial ports for the Sun386i. The 80186 processor on board relieves
	   the system processor of routine I/O processing.

	   Technical specifications:
	     8 port version only
	     8 mhz 80186 processor
	     128k dual ported RAM
