#8143 New Serial Interface
If you are using an optional interface, it may be necessary for you to
alter the communication protocol of the printer or the computer so
that they can communicate properly. In most cases, you should use
the information in your optional interface manual or your
computer’s manual to match the computer with the interface.
If you are using the #8143 optional interface board, make sure that
you read through the section below on baud rate selection. You may
also want to see the sections on handshaking timing and error
handling for interface information specific to your printer.
