Yes, this and the confirmation that I have 32 KBn:s So I need to make
in my TTY.CMD to set scope on all 32. I only have a small hand full of
to telnet in with, but each of those can telnet in more than once...

whoo real multi-user... feel the "comunity" :^)

Now if I can only get teco and tty.cmd to cooperate... (see "A
different rsts question")

Thanks for all the help, All of you. Very much.
