Re: [NTLK] NCU Connection Error code -1

I've been using an application called CPUKiller. I find that it works like a
charm. It has the same type of slider interface, but you can actually
specify an application to use as a default and it will start with that
application open. Perfect for NCU. I get consistant, reliable connection at
57600.

Thanks for the help. I have just spent the last couple of hours tweaking

the slowdown slide bars and trying out different combinations of

communication speeds with varying degrees of success. The best I've got is

about five seconds of backup. Is there a better way than the Monte Carlo

(i.e. pot luck) approach that I'm currently taking to get a stable

connection?

Supplementary questions:

Presumably the "speed" slider slows down the CPU, but what does the

"reaction" slider do? May be if I understood its meaning it might help me

to make more intelligent choices.

Thanks in advance

Tony.

This has been mentioned a few times, I'm surprised it's not mentioned in the

FAQ (Victor or Paul?). With a 1 Ghz machine, you'll probably have to run

"SlowDown.exe" one or twice to let NCU keeps up with the serial data

pipeline. Available on UNNA <http://www.unna.org/>.

brain dump n.: [common] The act of telling someone everything one knows

about a particular topic or project. Typically used when someone is going to

let a new party maintain a piece of code. Conceptually analogous to an

operating system core dump in that it saves a lot of useful state before an

exit. "You'll have to give me a brain dump on FOOBAR before you start your

new job at HackerCorp." See core dump (sense 4). At Sun, this is also known

as `TOI' (transfer of information).
