TelnetDLX with Cisco PIX and SSH (wodSSH / wodSSH.NET)

Has anyone run across this problem? I'm using wodTelnetDLX and whenever I use either version of SSH or any emulation type to connect to a Cisco PIX firewall it will authenticate and give me the standard > prompt but after that no data passes. The control is still in a connected state and it doen't generate any errors it just won't send anything to the PIX (either via manual typing or .send method) and it doesn't receive any data. I can manually disconnect and reconnect and it will log in again just fine then stop again. I can connect to any other SSH servers (Netscreen, Unix, Linux) just fine with no problems. I've tried it on three different PIX's with the same results. Anyone run across this before?
