Last week I posted a query about CR processing. I was able to telnet
to TWG telnet from a 4.3 BSD system only if I was connected on a 
direct line. I was not able to connect when I was logged into the BSD
system via a Bridge CS/1. 

The problem stemed from the connection between the Bridge CS/1 and
the BSD 4.3 telnetd. The CS/1 was incorrectly sending \r\n as the
line terminator instead of the correct \r\0 sequence. The BSD telnetd
converted the \r\n sequence into \n and sent that into the pty. The
\n was passed on to TWG telnet which interpeted \n as "delete the 
word to the left of the cursor". So much for logging in.

I have since obtained a new release of Bridge CS/1 software (version
13000) which fixes the problem. They now offer the option (per port)
of sending \r\n or \r\0 as the line terminator. 

I thank the many people who took time to respond. It made life
much simpler.
