Epson Multi-mode Data Controller MFJ-1278B Manual De Usuario

There are several terminal programs available for the Color Computer.  You will probably 
want to use a commercial program (rather than writing your own) since the Color Computer 
has a "software UART" that is difficult to program in BASIC. 
 
Some of the terminal programs available are COLORCOM 64, AUTOTERM and 
RICKEYTERM (for Coco III).  Others are WIZ and XTERM  for OS-9.  

These computers have built-in terminal programs in ROM.  Consult your computer's 
documentation for instructions in their use. 

This section describes the pins used on the MFJ-1278B RS-232C serial port connector.  It is 
intended for users with special applications requiring hardware handshaking.  This 
information should not be needed by most users.

The Frame Ground pin is provided for attachment to the chassis of the MFJ-1278B 
and the chassis of the attached device (computer or terminal).  This pin is available 
at a feed-through hole on the MFJ-1278B PC board near pin 1 of the serial 
connector.  It is not electrically connected anywhere else on the MFJ-1278B circuit 
board.
