Do I need a specific font to render carriage returns properly? This
is from acme on p9p: http://cl.ly/image/0H0n2F1s1e0e

The same behavior is visible in 9term as well. I have the issue both
on p9p and vanilla plan9.

Thanks.

no. changing the font also wont get rid of the ansi escape
codes. plan9 text console is not a tty. read the recent
(ssh) posts on this mailinglist as it touches the topic
of chaning the terminal output to something acme/plan9
can handle.

could you define "properly". that looks right to me.

unix/plan 9 don't use nl+cr. the carrage return harkens
back to the days when the console had an actual typewriter
carrage which needed to be sent back to the left. in the
very old days, even before consoles with printer heads,
there was a manual return lever and a linefeed key. since
the early 1960s (half a century!) return, has, uh, been return.

my adsl router has a telnet interface that won't dumb down (i.e. be
sensible). it is more than tedious watching it try to backspace over
stuff and move the cursor about. hey guys, don't do that crap!

You can make a telnet client that dumbs down the stream to your terminal. Telnet is trivial to implement.

Brilliant! Write a program because the router is stupid. Anything else
you would like me to write while I'm at it?

That's a bit elaborate. vt(1) might be easier.

Indeed. Though I'm waiting for the trivial implementation that does
something imaginative with the batshit practice of overwriting lines
using CR without LF.

now that you mention it, vt is missing the flyback transformer whine. you
should be able to *hear* what's displayed.

Perhaps decwriter(1) should be on someone's list. Then we can all
not-sleep at night. And if things are running too fast the 110 baud
switch could be used.

make sure to include the ever-popular LOC switch. just
to see if the n00bs are paying attention.

perhaps it is there an you are no-longer able to hear it? :-)

I can no longer hear line rate in the UK (15.625kHz).

solos. that mouse has some pipes.

If that is a "win" it looks to me like you should be able to fix that
with unalias -a. Otherwise you should be able to tell whatever
program that is to not use ansi escape chars. I'd look for colorize
or something like that in the documentation or look at the TERM=
environment variable.

Cheers,
Ian
