Interactive Mode

Interactive mode enables two-way communication between a
9401 printer and a host. With interactive mode, a host can
•
send a message to the printer operator.
•
request and receive information from the printer
operator.
•
use the printer as a data collection device.
NOTE: You cannot use protocol converter models 2071,
2072, 2073, and 2074 in interactive mode.

Processing Overview

The following procedure summarizes one transaction between
the host and printer in interactive mode
1. The operator sets the printer in Print mode.
2. The host sends the printer a data stream in the form of an
exception packet (see "Exception Packets"). If it uses
XON\XOFF flow control, the host must precede the
datastream with an initial XON.
3. When the printer receives the packet, it returns a status
message (see "Printer Status Codes"). It also enters
interactive mode and is ready to transmit data to the host
after the host sends a prompt.
4. If the host requests a response from the printer, the
6
operator enters the response at the printer (up to 30
characters) and presses one of the following keys:
8
•
(to send entered data)
•
(to respond with no data).
NOTE: The printer appends a carriage return to the end
of the reponse (even if the operator enters no
data).
