I would like to request that there be a way in the xen console
to send the escape char. The problem I faced was that I did:
xl console <dom id>
domU> telnet <device>
...
At some point, I realised that I wanted to send Ctrl-], which is
the standard telnet escape char to the telnet command. But, of
course, the xen console ate it and exited. A Google search and
asking a developer that was hanging out in a private chat where I
often hangout didn't produce any answers. So, then I looked at
tools/console/client/main.c in Xen 4.5.1, which is the latest that
I had at hand, along with master in your gitweb, I found the
following code:
212 if (FD_ISSET(STDIN_FILENO, &fds)) {
213 ssize_t len;
214 char msg[60];
215
216 len = read(STDIN_FILENO, msg, sizeof(msg));
217 if (len == 1 && msg[0] == ESCAPE_CHARACTER) {
218 return 0;
219 }
Thus it would appear that there is currently no way to send the
escape char to the domU. I would provide a patch, but I'm not sure
what would be the best way to make the change.
