I have a program that just displays a line of text.
My question is:

When running locally, if i use writeln('My Text') it works fine.
the next writeln('test') writes left justified on the second line.

When I run the same program over a telnet connection (in linux xinetd), the second write line doesnt left justify. I am sure it has to do with ANSI
control characters but I cant find the unit, library, or info to reset the columns, and also enable ANSI color.

Anyone know how?

that's correct... writeln sends the CRLF which moves the cursor down one line and returns it to the left margin...

xinetd), the second write line doesnt left justify.

what terminal are you using? check your terminal settings... i forget what it is called but there is generally a setting for LF or CRLF... it sounds like you
just have LF which will simply move the cursor down a line but keep it in the same column position...

I am sure it has to do with ANSI control characters

what makes you think this? especially if you are not sending any ANSI stuff...

but I cant find the unit, library, or info to reset the columns, and
also enable ANSI color.

based on this is why i say "not sending ANSI stuff" above... if you don't have a unit or whatever for ANSI then it shouldn't come into play...

I viewed it with netrunner and I don't see any settings that should cause it. Also does it with regular telnet in Linux

Your telnet client may be expecting both a carriage return and a line feed character.

I suspect that if you do something like this:
writeln('one');
writeln('two');
writeln('three');

The output would be:
one
two
three

If that's the case, try this:
writeln('one'#13);
writeln('two'#13);
writeln('three'#13);

You should get:
one
two
three
