RE: Interactive subprocess output not echoed until process ends

Ah, some key evidence here:

http://www.gnu.org/software/emacs/windows/faq7.html

See the section about buffering.  It seems some of the interactive
subprocesses buffer their output -- and I'm seeing that if I get a
subprocess to queue up a decent amount of output (seems about 1k for
telnet command mode), it'll spit out the output.

Now how to get it to not buffer...!

This is likely to be either a misconfigured or out-and-out broken shell
rather than an XEmacs problem.  Most of the XEmacs Windows developers
live in shell buffers.

For me (Windows 2000, XEmacs 21.4.12, 21.5.12), starting XEmacs and
typing M-x shell does the trick.  Shell is Cygwin bash.

Please send a full bug report using M-x report-emacs-bug, and don't
forget to tell us the values of your SHELL and COMSPEC environment
variables, and (if available ) the version of the shell.
