Sample settings for 3151
This document applies to AIX Versions 3.2.3 through 3.2.5.
Function keys not working
Function keys may not work for the following reasons:
- AIX requires "Turnaround Character = CR" in Communication Setup menu; the
default is ETX.
- Perhaps you are using 3151 Model 510/610 and a host application that
requires redefinable function keys. The Model 510/610 DOES NOT support
redefinable function keys. Recommend using models 310/410.
- An application (example UNIPLEX) may redefine function keys on models
310/410 and not reset them back to default values when exiting. The host needs
to transmit 3151 "Set All Default Function Keys" command (ESC SP t). Operator
can reset function keys in DEF F setup by pressing the Clear key.
Insert key not working
If the insert key does not work, change the INSERT CHARACTER setup option
from MODE to SPACE.
Double characters displayed
If double characters are displayed, change the OPERATING MODE from CHAR to
ECHO.
Double prompt when enter/return key is pressed
The New Line option must be set to CR, not CR/LF. If it is not, it may cause
a double prompt when the Return/Enter key is pressed. The New Line option can
be changed either from the setup menus or from the host.
Setup:
- Keyboard setup menu. (Models 110, 310, 410 only)
- Select "Default" in Function setup menu.
Host: Set Control 2 Command: ESC ! 9 ( J
3151 locks up
If the display locks up:
- Turn on "Status Line" either from keyboard or from setup. This provides
additional information. The following items may be displayed on status line:
-
HOST BUSY
- Host told 3151 not to send data to host. Problem must be corrected at
host.
-
KEYS LOCKED
- Host sent "Keyboard Lock" command. Host must send "Keyboard Unlock"
command. Problem must be corrected at host.
-
HOLD SCREEN
- Operator pressed "Hold" or "Pause" key; must press "Hold" or "Pause" key
again.
- It may be that the operator accidentally pressed Ctrl-S (XOFF); Press
Ctrl-Q (XON) to fix the problem.
3151 does not communicate with host
If the 3151 does not communicate with the host:
- Turn on "Status Line". If "COMM NOT READY 2" is displayed, change "Line
Control" = IPRTS.
- Host cable may be attached to the auxiliary port rather than the main port.
The main port is on the right-hand connector ("right hand" as you are looking
from the back).
- The Transmit Data, Receive Data pins may not match the host communications
port. Check pin configuration on the host system.
- The host system may not have the communications port enabled.
- If the second session is not working with the Connectivity Cartridge in
Dual Session by Dual Port, the directions of pins 2 (TD) and 3 (RD) are
reversed. Switch pins 2 and 3 on the communications cable attached to the
Auxiliary port.
Missing or lost characters
Missing or lost characters may be caused by a pacing problem. Reduce line
speed to 2400 or 4800 to confirm that the problem is pacing. Activate pacing
at the 3151 and the host.
Lost setup values
If setup values are lost:
- The host could be changing setup values by various 3151 commands: Set
Control, Create Viewport.
- Perhaps the user changed the setup options in the setup menu, but never
performed the "Save" operation (move cursor to "Save" and press space bar).
Cannot get into setup
If you cannot get into setup:
- The problem may be a mismatch of keyboards with the video element.
- If you have a 110 video element with a 310/410/510/610 keyboard, press
Ctrl-F4 to enter the setup.
- if you have a 310/410/510/610 video element with a 110 keyboard, it is
impossible to enter the setup.
- It may be that DEC VT200/VT100/VT52 emulation is selected and the keyboard
does not have the DEC Keycap kit. Press the F3 key, the location of the setup
key when in DEC emulation.
Cannot print, not printing correctly
If you cannot print or if printing is incorrect:
- Make sure the printer is a serial printer, not a parallel printer.
- Make sure the correct cable is being used with printer. Note the
directions of the Receive and Transmit data pins.
3151 displays backward question marks
Backward question marks are caused by a frame error; the parity, word
length, stop bits, and line speed must match the host system.
The (*,/,-,Alt,Ctrl,Page Up,Page Down) keys are not
working
With a model 510/610 in ASCII Mode, the keyboard becomes a 310/410 ASCII
layout. This creates the symptom of particular keys not working. Refer to
pages 3-1, 3-2 of the 3151 Guide to Operations, Models 510, 610.
Line drawing characters do not display
Line drawing characters not displayed is a result of a character mismatch
between the host and the 3151. 3151 offers the following character sets:
Special Graphics, PC 00437, PC 00850, ISO 8859/1.2. Determine the character
set defined in 3151 and determine what the host is expecting.
3151 has extra blank lines
To get rid of extra blank lines, set "Auto LF = OFF" in the general setup
menu, or from the host use "Set Control 3" command: ESC " 9 = b
Application is not displaying correctly
If an application is not displaying correctly, it could be that host
commands do not match the 3151 settings. 3151 is set to IBM 3151 and host
could be using DEC VT100, WYSE 50/50+. Use 3151 Transparency mode to determine
what host is sending.
Cannot redefine function keys
With model 510/610, redefining function keys is not supported.
Constant beep
A constant beep may occur if you are using a cartridge with model 110.
Cartridges are not supported with this model.
Screen is wavy
If the screen is wavy, change the refresh rate to between 50 and 60 hertz.
Press Ctrl-Shift-Hold. 3151 displays keyboard test pattern. Press Ctrl-F10.
3151 displays A or B (refresh rate). Press F1 to toggle between A or B. Power
off and on 3151.
3151 displays "HJ"s in CATIA
CATIA supports VT100 emulation, but the IBM 3151 is set to IBM 3151 mode.
The VT100 commands are not compatible with IBM 3151 mode. Therefore, 3151
requires either IBM/DEC or Connectivity cartridge which offers VT52, VT100 or
VT200.
3151 backspace key is not working
If the backspace key does not seem to work:
- When using DEC emulation, the Backspace key is a DEL key, as it is on a DEC
terminal.
- It could be that the application is causing the unexpected result.
Setup values of one 3151 does not match other 3151
The 3151 offers many models and eight cartridges with over 20 emulations, so
the setup value could differ among 3151s. Compare the machine mode of each
3151. Possibilities include:
- Could have two different models 110 versus 310/410 versus 510/610.
- Perhaps one 3151 has a cartridge and the other does not.
- Both 3151s have cartridges, but they may be different types of cartridges:
IBM/DEC, Expansion, Connectivity, or WYSE 50/50+.
- Both 3151s have the same cartridge, but the machine mode is not set the
same.
Review your 3151 documentation.
