   I'm running JNOS2.0 on DOS.  LOOK works perfectly for me.  Scrolls 
correctly.  Lines wrap correctly.

   The LOOK command as far as I know is *NOT* used to send text to the 
user.  It is just that, a way to "look" at what the guy is doing.

   I can scroll through my history of commands and hit enter to re-execute 
then.  I do this ALOT with the 'conv list' command, as I watch what 
Hamgates' CONVerse links  are connected to me.

   Dunno what SHIFT+UP-ARROW does....  You'll have to fill me in on that

   How *exactly* did you try to "chat" with him???

   I usually go into the CONVerse bridge and issue the "/i <callsign>" 
command to Invite him to join me on the CONV bridge.
