This is a well known problem. A quick glance at the newsgroup finds some things:

• Use the tshell
  article
• Set up correct terminfo (and hope that the program you use looks at it).
  article
• Have a look at the eterm package in your distribution (I'm not sure if this is XEmacs only). This package contains the tshell and the doc says it's a realy ANSI terminal: * Uses standard ANSI (vt102) escape sequences.
• Here is a longer discussion of the topic.

Good Luck!
