Re: sysinstall and serial consoles

I meant sysinstall generating cons25 output.  But there were recently a
lot of terminfo changes that may have caused this.

Oh.  sysinstall asked if I wanted ANSI, vt100, cons25, something else
related to FreeBSD console, or xterm.  Most of those options were wrong,
which is the bug that I think I'm trying to report.

sysinstall and serial consoles

2002-12-11 Thread Bill Fenner

I installed 5.0-RC1 on a Sun Ultra-60 a couple of days ago.
The biggest problem that I ran into was terminal emulation
inside sysinstall.

I normally do most tasks inside screen, so I tried selecting
the vt100 emulation (since that's what screen tries to be).
However, it uses something that screen doesn't emulate, so
the screen was full of OOPS where screen didn't know what
to do.

Fine, that's screen's problem.  I tried ANSI, and had two
problems:
1. There was no reverse video, so it was impossible to determine
which option was selected.
2. Using the arrow keys resulted in sysinstall asking me if
I really wanted to abort the install (presumably it thought I
hit escape).

Ok, so that one might have been screen's problem too, so I'll
just do it outside of screen.  Since I was running tip from
an xterm, I figured it made most sense to choose the xterm
terminal type.  Nope, no luck, it was nice and colorful and
drew the lines, but the menu did not line up so the screen got
pretty much filled with gibberish after a couple of attempts.

Someone said that the problem was the oxtabs stty setting, so
I tried xterm with both oxtabs and -oxtabs and had the same
experience with columns not lining up.

So, I tried ANSI from within the xterm.  That had the same problems
as screen -- no reverse video and arrow keys asked if I wanted to
exit.

So, finally, I tried vt100 from within the xterm.  That worked.

I think it's fairly likely that people will be installing FreeBSD
on headless suns; I think it's fairly likely that most of these
people will go through one or more of the painful iterations that
I went through before happening upon the magic correct combination.

My suggestions:
1. Look into the reverse video problem when selecting ANSI terminal.
2. Look into the escape character problem with arrow keys and ANSI terminal.
3. Remove the xterm option, and call vt100 vt100 or xterm.  (Or fix
   what is wrong with the xterm termcap).

screen(1) says Each virtual terminal provides the functions of a DEC
VT100 terminal and, in addition, several control functions from the ISO
6492  ... and ISO 2022 standards 

I took that to mean that it provides a vt100 interface.  That's also
been my experience in the last 8 years of using screen.
