baldwin@usna.MIL (J.D. Baldwin) (12/13/89)
A week ago, under the subject: "What is with this character set?" I asked the following question (abridged): [article <314@usna.mil>] >Sometimes, when I accidentally list out a binary file, >I get the usual garbage characters on my screen. Then, when I stop the >listing (either by waiting for it to end, or by hitting ^C), everything >I type (or is typed back to me) is in "garbage" characters--the character >set seems to have been mapped to the upper half of the IBM extended character >set. > >Nothing I do (Alt-R for reset, clear, stty, etc.) clears this problem, >short of logging off and logging back on. I should have written, ". . . short of terminating the session and starting another one." In any case, I got several answers: ------------------Answer #1 (abridged)------------------------ From: hamlin@BLACKBIRD.AFIT.AF.MIL (Joe Hamlin) >Try the following (you essentially type this in "blind", since >the characters get echo'd as "garbage"): > >echo "^V^O" > >What we're doing is sending a CTRL-O to the terminal. Just typing >CTRL-O doesn't work. The "^V^O" is actually typed as >QUOTE CTRL-V CTRL-O QUOTE. This was the first solution I tried, and it worked just fine. -----------------Answer #2 (abridged)------------------------- From: andyb@coat.com (Andy Behrens) >My terminal (a vt52 lookalike) uses <esc>F to select alternate >characters and <esc>G to select the normal set. Look at your termcap >entries for as= and ae= respectively. Yep. Sure enough--my /etc/termcap entry for vt100 reads ae=^O:as=^N:... This fits in nicely with Joe's suggestion about sending a ^O to the terminal to select the normal character set. Experimentation confirms that sending a ^N selects graphics characters. -----------------Answer #3 (abridged)------------------------- From: Joel Spolsky <spolsky-joel@YALE.EDU> >. . . make a little file containing the >following sequence: > > <esc> ( B <esc> ) B > >Then if your terminal freaks out, just cat this file. Worked fine as well. I'm not too clear on why, but Joel mentioned that he dug it out of an ANSI manual. -----------------Answer #4------------------------------------ From: me While playing around looking for answers, I discovered the unix 'reset' command! Also works. Thanks to all who responded. Hope this helps someone else out there. -- From the catapult of: |+| "If anyone disagrees with anything I _, J. D.
