yes it does have the space - sorry. does it make a difference if I use tn.r=
ead_until vs tn.read_all?  will it close the connection or not accept a wri=
te command if I  dont read_until?  the fact that I get a traceback error wh=
en I read_until and I get ",,," when I use read_all - does this mean the co=
nnection has been closed?

also when I try tn.open(host) it will give me the welcome screen with the w=
ords "session 1" included in the string.  if I then immediately try tn.open=
(host) again it will give me the same welcome message with "session 1"  cou=
ld the connection be closing before I get a chance to write the user name?
