That depends on what you mean by "lwip core": in our "language", "core" 
means the code below "lwip/src/core". For these, Kieran's answer ("no") 
is correct: multithreading is not supported at that level.

However, from your post, (and from guessing you are not familiar with 
that definition of "core"), I you might rather mean "can lwIP handle 
multiple sequential- or socket-API connections at a time?". This 
question has to be answered with "yes". There should be no limitiation 
to run a (socket) telnet server together with any other sequential or 
socket API program (as long as every connection is used from one thread 
only, but that's a different story).

If it doesn't work for you, there's either something wrong with your 
port (the adaption layer between lwIP, freeRTOS and your hardware) or 
(maybe more likely) the configuration options in your lwipopts.h limit 
the available resources.

Since your question is rather port-dependent, it might be better off in 
a lwip-freertos-related mailing group than here (although there are some 
people using freertos here, too).
