terminal weirdness?

I telnet'd into port 1080, pressed enter, and got disconnected...fine. But, after I got disconnected "VT102" was displayed at my command prompt. I figured it was just 'misplaced output' or something from telnet, but when I hit enter I got 'command not found'. I don't understand where VT102 came from, and why my shell interpreted it as valid input from STDIN. I checked env and term=vt100. Just to do it, I strings `which telnet` | egrep -i "vt102" and nothing was found. Could this be something sent from the proxy server? If so, can it be changed arbitrarily (rm -r *)? I checked a handfull of other proxy servers for the same behavior but found nothing. I tried this from a Red Het 6.2 box and a BSDi 4.0 box, both yeilded the same results. Below is a snip of what happened and the results from nmap. <snip> [root@unix /root]# telnet x.x.x.x 1080 Trying x.x.x.x... Connected to x.x.x.x. Escape character is '^]'. Connection closed by foreign host. [root@unix /root]# VT102 bash: VT102: command not found [root@unix /root]# </snip> <nmap> Port State Service 67/tcp filtered bootps 137/tcp filtered netbios-ns 138/tcp filtered netbios-dgm 139/tcp filtered netbios-ssn 1080/tcp open socks TCP Sequence Prediction: Class=trivial time dependency Difficulty=35 (Easy) Remote operating system guess: Windows NT4 / Win95 / Win98 </nmap> Thanks in advance for any input.
