RE: escape sequences/telnet

Argh...  That was the problem.  The system was using an older 7.x version.
Tested with the 8.1.11 and its working well.

Subject: Re: escape sequences/telnet

what version are you running?  i made a conscious effort to remove any
"chopping" of the data so that if the client reads N characters from the
user (in a single read()), then it passes all the way from client code
out server code as a N character write() out the other end.

i just did a simple test with 8.1.11 on solaris and the debug log shows:

[Wed Apr 27 08:04:19 2005] conserver (9106): DEBUG: [cutil.c:1143]

i was connected to a web server (hey, it's a tcp port) and you can see
it being read from the client port (fd 6) and sent to the "console" (fd
5).  i hit the key twice, hence the double output.

so, if you're using 8.1.11 and seeing issues, try running conserver with
-DDD and lets look at some of the output like above.  if you're not
using 8.1.11, upgrade.  i don't know when things got fixed, exactly, but
it looks like it is.
