I wasn't able to duplicate a mini-DOS running eXceed 6.0.2.0 on NT 4.0 SP4.
Steps:
On NT machine, opened xterm session
Went to box that I just opened the session with, type in TELNET <my_ip_addr> 6000
The eXceed program hung for about 2 minutes as the host tried to connect to it, but everything else still worked in NT.
After attempting to connect, it will say it is connected for about 2 seconds and then states "Connection closed by foreign host".
After that the eXceed session resumed and I was able to close out gracefully.

This is regarding Hummingbird's Exceed X emulator v5 (and possibly v6)
running on Windows NT. I haven't tested Win95/98.
The Exceed X server allows inbound TCP connections on port 6000 from the XDM
host. If someone uses telnet from the XDM host to connect to a PC running
Exceed on port 6000 and enters any garbage text, the X server will hang and
the Exceed session is frozen for good.
I have notified Hummingbird via their tech support web site but have not
received a response yet.
