How can I define a terminal-attached printer for a ibm3151 connected to
a 8-port controller? The printer works fine while the 3151 is connected
to native s2 port. I heard something about there are some changes in
terminfo definitions for the terminal: mc4 and mc5.
ANSWER
Terminal attached printing through the 8-port adapter can be
configured similar to that of any other adapter configuration
(e.g. 16-port, 64-port, 128-port...) with the only exception
that the TERM type must be set to IBM 3151 or it will not work.
Use the following steps to configure TAP:
1. You must belong to the 'printq' group or obtain 'root' authority
on the RISC.
2. Getting into SMIT
From the command line enter 'smitty'
Select the following options in the order that they appear
Devices
Printer/Plotter
Manage Local Printer Subsystem
Virtual Printers
Add a Virtual Printer
OR
Enter the SMIT fastpath 'smitty virprt' and select
'Add a Virtual Printer'
3. Select option 3, 'Printer or Plotter Attached to ASCII Terminal'.
Terminal attached printing works with AIX versions 3.2.3E and
above.(?) Notice that it is not necessary to define a physical
device to the RISC.
4. A list of 'available' TTYs will be displayed along with their
unique addresses. Determine which TTY the printer is connected
to and select the appropriate number.
5. Select the type of printer that is being attached to the ASCII
terminal. If the printer is not supported by AIX you may wish
to configure the printer as an ASCII printer.
6. Configure the virtual printer.
7. You can now print to the terminal attached printer by enter the
following command from the command line on the RISC System/6000:
enq -P
Where is the name of the queue that is
associated with the terminal attached printer, and where
is the name of the file that you want to print.
The mc4 and mc5 attributes are defined as:
mc5=Value Instructs the terminal to send all data to the AUX port.
(Printer ON)
mc4=Value Restores output to the terminal. (Printer OFF)
For supported terminals, the control sequence values are predefined
in the terminfo database. The control sequence values are terminal
specific. For example, the printer command sequences for an IBM 3151
terminal are:
mc5=.P.R
mc4=.P.T
In this example, .P.R refers to the Ctrl-P Ctrl-R key sequence;
and .P.T refers to Ctrl-P Ctrl-T key sequence.
No changes should need to be made to these values in order for
Terminal Attached Printing (TAP) to work.
The only other problem to be concerned with is ASCII terminal and
printer performance when printing large files to the terminal
attached printer. Since the ASCII terminal and the terminal
attached printer need to share resources, performance will degrade
on both devices when printing large files. This is also a direct
result of the 8-port adapter having a small buffer.
