Telnet versus telnetlib

[Sean Davis]

I have used command-line telnet to login to a host, paste into the
window a small XML file, and then ^] to leave the window, and quit.
This results in a page (described by the XML file) being printed on a
printer.

When I do an analogous process using telnetlib, I get no debug output,
and most importantly, when I send the XML file to the host, I get no
printed page.  Unfortunately, I do not have access to the host to do
troubleshooting there, so I have to "feel" my way around.  Any
suggestions on what might be going wrong?

Thanks,
Sean
