Double carriage returns on IBM 3151 terminals.

900918-mlb01
INTRODUCTION:
=============
This knowledgebase entry presents the steps to take
inthe event of double carriage returns on the IBM3151
terminal, inside and out of Progress.

WHY YOU NEED TO DO THIS:
========================
On the IBM3151 terminal, login as root, at the root prompt
type SMIT and press return. A menu will appear. Choose
Devices from that menu and press return. Another menu will
appear, choose tty from that menu and press return. A window
will appear at the bottom of the screen which displays the tty
for that terminal, tty0. It will be highlighted just press
return. Another menu will appear, choose settings and
characteristics. A list of parameters will appear. The
culprit is not currently displayed. Press the down arrow
until Terminal type is displayed. To the far right there
should appear a type name between brackets like [dumb].
Change it to read [ibm3151] and finish out of SMIT.

The next thing to do is to comment out the Si and Se
parameters from the ibm3151 Protermcap entry. Copy
Protermcap to another directory (make sure you change
your PROTERMCAP environment variable to point to the
new location). Now vi your new copy of the protermcap.
Find the ibm3151 entry (/3151) then find the :Si
line. Insert a . after the : and before the S. This
effectively comments out the Si string. On the next line
(usually) you should find the :Se string. Same thing,
insert a . between the : and the S to comment it out
as well.

This should solve the cr/lf problem for the terminal
(the double carriage return when you press return) and
stop Progress from reinitializing the terminal every
time the user goes in and out of Progress.
