Some years ago I wrote Haskell bindings to libtelnet ( https://hackage.haskell.org/package/libtelnet ) and a reflex wrapper around them ( https://hackage.haskell.org/package/reflex-libtelnet ).

Perhaps they are useful to you. If you need dependency bounds relaxed or revised to work on modern GHCs, let me know and I'll take a look.
