- Terminal emulation would be handled with a subset of the XPR protocol
- called the XEM (external emuluation) spefication. The best examples of
- these that I've seen are released with the package called TERM. I'm not
- familiar with Atalk, so I don't know if it supports XEM libraries.
-
- The concept is fairly simple : Figure out where the terminal's screen is,
- open a window on it, and make use of the xpr_sread(),xpr_swrite() to talk to
- the modem/etc. Please look for the xprotocol2.doc file that describes
- the XPR 2.0 specification.
-
- BTW: If you wish to get involved with future enhancements to XPR/XEM/etc,
- please join the XPR mailing list.
