Using tcpsvd for a remote shell

Hi,
after having managed to get tcpsvd and sslio working on the embedded
system i'm developing on, i'm considering getting rid of some other
apps such as a telnetd (named shelld, unmaintainted code...)
What do i need to do to use tcpsvd to create a proper telnetd
replacement? With sslio it works except for the sh thinking that i'm
non-interactive even when i give the -i option, and not yet having a
"login" inbetween.
Any hints, what do i need to do for this to work properly?
(Do i need to use a pty? what is the best way to create such?)

Greetings,
Erich Schubert
