I believe the number of connections to those MOXA is limited to a small
number.
The MOXA must consider that the maximum number of connections is
currently open. Hence, the telnet to port 23 or 80 or any other do not
work.

To close the connection/socket on exit, you have to modify your iocsh.
There was a thread on how to do this not so long ago.

Hope this help,
