I have the following problem:
When I am working on a SUN3 with GNUEmacs (17.64), I can use the Meta flag.
But if I 'rlogin' to the same sun with the same account, it doesn't
work any more. Is this a known bug (of rlogin) or am I making some mistake?

The problem with meta keys not working over rlogin is that the rlogin only passes seven bits per character, thus losing the meta bit. I have a fix for this. It is a little filter that translates the key stroke meta-x to the pair of keys ESC-x for all x. I use it as a filter whenever I'm using telnet or rlogin, and the behavior of the meta keys is correct if I'm using an emacs-like tool on the remote machine. (I'm using it this instant, as a matter of fact.) If you're interested in this, send me mail. If there is sufficient interest, I'll post it to mod.sources, otherwise I'll respond to the mail requests individually. Tim Freeman Arpanet: tsf@theory.cs.cmu.edu

An option of rlogin tells it to pass 8-bit bytes, instead of
dropping the 0200 bit. I have seen it undocumented in our VAXen/4.2
but documented in our Sun/2.0 machines, yet it works in both, so I
would give it a try even if your manual page doesn't mention it.

Note that the -8 option tells rlogin always to use raw mode, and thus makes ^S/^Q virtually useless. Nor should any of this be necessary: rlogin has built in a protocol by which it can detect that the remote machine wants an eight bit data path, and will switch in and out of raw mode as appropriate. Unfortunately, the 4.2 rlogin (on which the Sun 3.0 rlogin is based) is largely broken. Install the 4.3 rlogin, with the 4.3 rcmd.c, on the Suns. -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 454 7690) UUCP: seismo!mimsy!chris ARPA/CSNet: chris@mimsy.umd.edu

Not all rlogins have this problem, apparently. The rlogin on my sun3/v3.2 passes meta to my vax/Ultrix1.2, and to itself, but the Vax/Ultrix rlogin won't pass it. It seems that this has been fixed in recent releases somewhere. The mapping META-<foo> to ESC <foo> won't do just the right thing in all cases - if you have the habit of terminating isearches with a meta-character, you will find the ESC terminates the search and the next character is inserted (or otherwise interpreted according to its binding). /jr
