Anyone knows how terminfo works in RedHat Linux

I have one customer using tinyterm with termcap with the emulation wy60w-42 in Unix and the display on the screen is 132 columns

I was told by Red Hat to use terminfo instead of termcap but i dont know how to use it

I know in Linux the directory /usr/share/terminfo

there are all the emulations, example in w directory I have all the wy* emulation

I said in my user profile


but still displaying 80 columns instead of 132

How can I solve this?

Just type "set" at the command line to see what TERM is set. You need to set TERM in user profile. The database of all the compiled terminal types must be pointed by TERMINFO.  To locate the database type "locate vt100". Check if you have wy60-42-w in the database. If not you can download the terminal source and compile using tic.

First, verify that your terminfo database actually has a definition for wy60-w-42:
env TERM=wy60-w-42 infocmp

Open in new window

You should see a dump of terminal definition.

Second, don't set TERMINFO, set TERM:
export TERM=wy60-w-42

Open in new window

Third, what is "it" that displays 80 columns (what application are you using)?

Is the file and the path correct /usr/share/terminfo/w/wy60-w-42 if this is correct you need to set TERM=wy60-w-42
