Epson 1010 Printer User Manual


 
#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.
For all other data transfer conventions, such as word structure or
communications protocol, use the information in the manual
supplied with your #8143 optional interface.
Baud rate selection
You can select baud rates from 75 to 19,200 BPS (Bits Per Second).
When setting the baud rate, make sure you use the bit rate selection
table for printers with buffers (in the #8143 interface manual).
For more information on the printer’s input buffer settings, see
Setting the DIP Switches in Chapter 3 of this manual.
Handshaking timing
When the vacant area for data in the input buffer drops to 256 bytes,
the printer outputs an X-OFF code or sets the DTR flag to 1 (MARK)
indicating that it cannot receive data.
Error handling
When a parity error is detected, your printer prints an asterisk (*).
All other errors, including framing and overnm, are ignored.
