Re: no color syntax highlighting in emacs over SSH

[Ajit Mylavarapu <ajitkart@stanford.edu>]

The TERM setting on the remote machine (Sun box) is set to xterm. You 
are right in assuming that I am doing an ssh to a remote Sun box and 
then running emacs.

Also, how do I find out more about termcap/terminfo entries on the 
Solaris box? (I dont know much about termcap/terminfo). And once I find 
that out, what should I do?

Thank you,
Ajit.
