Full-blown telnetd:
# ./busybox telnetd --help
BusyBox v1.7.0.svn (2007-06-04 20:25:28 CEST) multi-call binary
Usage: telnetd [OPTION]
Handle incoming telnet connections
Options:
-l LOGIN Exec LOGIN on connect
-f issue_file Display issue_file instead of /etc/issue
-p PORT Port to listen to
-b ADDR Address to bind to
-F Stay in foreground
-i Run as inetd subservice
You probably have CONFIG_FEATURE_TELNETD_STANDALONE unset, and therefore
your telnetd wolks as if -i option is active.
Testing...
# ./busybox telnetd -i

shadow login: _
Bingo.
