Rs-232 And Rs-422 Serial Interface Configuration - IBM 6500 User Manual

RS-232 and RS-422 Serial Interface Configuration

Your printer is configured as the factory to match the interface you specified. By
using the operator panel, you may verify and change several interface parameters
to meet specific application requirements.
Refer to "RS-232 and RS-422 Serial Interfaces" on page 206 for RS-232 and RS-422
parameter descriptions and information for selecting values for the following
parameters:
RS-232 and RS-422:
v Baud rate (data rate selected from the operator panel)
v Data Bits (7 or 8 Bits)
v Stop Bits (1 or 2 Bits)
v Parity (None, Odd, Even, Mark, or Sense)
RS-232 only:
v Data Terminal Ready logic
v Request to Send logic
Some application programs require a unique configuration. If the printer is not
working properly in the configuration you selected, contact an IBM service
representative.
One Char Enquiry
When enabled, and the IGP feature is available, a status byte is sent back to the
host when the poll character or the command SFCC enquiry is sent to the printer
(serial interface only). The poll character is received and the status byte is sent
whether the printer is online or offline. The SFCC enquiry will only be processed
when the printer is online.
Poll Character
This option is used when One Char Enquiry is enabled and the IGP feature is
available. Whenever the printer receives this character, it sends a response to the
host indicating the current state of the printer. It may be configured from 0
through 255. The default value is 0.
