I have two questions, aptly-stated by the title of this thread. My first question is about using the global CALCnet client program I downloaded from Cemetech.net http://www.cemetech.net/programs/index.php?mode=file&path=/win/gcnclient.zip. Reading through the included readme-style PDF document, I understood basically how it works. 

I’m trying to connect my calculator to the internet using Gossamer and the gCn Client software. To get to this work, the way I understand it, I need to run the gcnclient.exe program with some command line arguments.
What exactly are the arguments that I would need to type in the command prompt to get it to work? So far what I have is :
>gcnclient.exe -n WebHub
-l (don’t know what to put here)
-s (no idea)
-p 4295
-d direct (not sure if this works yet)
(Obviously without the carriage returns)
So yeah. That’s what I would like cleared up about that.

My second question is, how do I make use of interrupts in Axe? What is some example code where interrupts would be useful? I kind of understand what interrupts are, but not completely.

Thanks.

Interrupts are basically events that are triggered every few assembly instructions, at a call frequency defined by the second argument of fnInt(.  The first gives the subroutine to be called every few cycles, the second is the speed.  Example:

fnInt(LOL,0)

Lbl LOL
  Disp "LOL"
Return
The word "LOL" will be displayed every few cycles.

It's not 5 times a second. It might be every 5 instructions. Maybe it's every 5 CPU cycles. I can't remember off the top of my head.

FnInt(LBL,FREQ) Turns the subroutine into an interrupt and then turns interrupts on. The frequency can be (fastest) 0, 2, 4, or 6 (slowest). L2 is used for interrupt data so do not use L2 for storage when using interrupts.

Seems to me the same thing Desolate has?

Do you know how I might set up an interrupt to do something once every second?

count the number of calls. When the interupt routine has been called 118 times at frequence 6 on a 83+, then do something

Example:
.timer
0->A
0->B
fnInt(INT,0)
Repeat GetKey(15)
End
lnReg

lbl INT
A+1->A
Return!If A=512
B+1->B
Disp B
0->A
Return

Thanks for the help, this is pretty awesome information.

Can anyone answer my gCn client question?

If you're on Windows, you'll also need to install the filter driver. Get libusb-win32 at http://sourceforge.net/projects/libusb-win32/files/libusb-win32-releases/1.2.4.0/libusb-win32-bin-1.2.4.0.zip/download, extract the .zip file, and run bin\x86\install-filter-win.exe

... <local_name> can be anything, but is often based on user name (I use "CalcHub", for example. The main idea is that you provide something unique.) You can ignore the -s and -p options almost always; they default to what's necessary to connect to the server Kerm's set up.

(To clarify: <local_name> refers to what's after -l.)
To use DirectUSB, you are correct in using "-d direct", but note that "-d d" also works and is shorter
