Telnet connection problem portserver8

I am connecting to the portserver on port 8 via the com port on a pc. Then I telnet to a network device. It looks like I am connecting to the network device, but I can’t enter any commands. It looks like the only command it will accept is the enter key. When I IP to the network device directly without going through the portserver it works fine. Any ideal what might be wrong?

Thanks
