Krisky,

I have reproduced your problem (script doesn't work with COM Port > 9). The section of the code that is causing the error is shown below.

[krisky68]

It relates to COM port numbers over 9, from the MS website CreateFile help:

I didn't see your last reply before I posted mine. I'm running XP, but the problem I was getting related to CreateFile, not the DBC

[aobrien]

Krisky68, thanks for finding/fixing that bug! It is likely to not have been resolved otherwise.

I also put the fix in for the NULL (0x00) data.

Everyone (receiving email notifications) should update their functions to include these two important fixes. See the notes dated 7/23/08 on the second post for more information.

How can the script be modified to send data instead of ASCII characters?

[aobrien]

The script, by default, sends and receives only data. Look at the second post... in the header of the code you will find this following...

I need to send this:
-without the (begin) & (end) of course

(begin)
%

O8()

%
(end)

If could someone could show me how, I should be able to manage from here.
(thanks in advance)

Hi,

Can someone upload the dll because the developer site is gone

Thanks

Guest,

Here is the code that will perform what you are asking. I don't have ability to test this at home, but it should work (famous last words).

0. Install ahk on your pc.
1. copy the entire code below and paste it into a text file
2. save it as .ahk
3. double click the file name
4. press the F4 key to send the characters on the serial port.

This is a good ASCII table that will tell you how to translate the ASCII characters to Decimal or Hex code which is what the script needs.
http://www.asciitable.com/

There are 2 different codes that can be used to send a {RETURN} 0x0A (New Line) and 0x0D (Carriage Return). Some text editors use one or the other or both. I'm not sure what your application requires so it might not be correct.

Good luck.

I'm wondering if this script can be used for my needs, but unfortunatelly my AHK skills are still very basic...
So, this is the thing: I'm using this program (SuperLab) to perform some experiments on visual perception. So far, I've been using AHK to send the mouse cursor to the center of the screen after any mouse click (so to allow the mouse cursor to appear always at that position at the beginning of each trial). But for some stimuli I would need the mouse cursor to be send for specific coordinates on the screen. Since the stimuli appear in a random order, the only way I could manage this would be to have SuperLab sending an instruction to AHK to perform that positioning of the mouse cursor. Luckily, SuperLab has the option to send a Serial Output (Including sending a String or ASCII values). Also, and since both programs would be run in the same machine, I can use a virtual serial port.
My question is simply out to "translate" a given serial output from SuperLab into an action within the AHK script (specifically, move the mouse cursor to x,y)? Would this script allow me to do that?
I can antecipate that I would have to do something around this logic: IF serial output = X THEN [instruction for mouse cursor]. But I can't figure out where and how in the script I can do such...
Thanks in advance.

Hi Max,

The following script probably won't work straight out of the box, but is a good start.

Read and understand the script until you get to the subroutines (don't go any further than that) then begin testing.

Good luck!

Hi aobrien!
First of all, thank you very much for the prompt reply along with the script.
However, I can't run the code. Everytime I try to it gives me an error message on a nonexistent function, namely Close_COM(COM_FileHandle). Moreover, it reports the error to be happening at the line 122.
Since this location is well below your comment "Don't touch this", I thought it would be better to ask you about this...
In the meanwhile, I've been looking through the rest of the code, and I'm pretty confident that it would work properly for my purposes.
Anyway, if you can give me a tip on this error, I would appreciate.
Thanks again!

hi

thanks for sharing this!

i got my plasma connected to my pc and use a software to switch it on/off. The software i use is kinda bloated/slow and i would like to try this script. Im a novis coder so i dont understand it fully. I want to send this:

"COM Settings","9600","O","8","1"
"C","Power On","9F 80 60 4E 00 CD","5"
"C","Power Off","9F 80 60 4F 00 CE","5"

*the 5 is some kind of delay i think 5ms ..?

Would it work to insert this data to your User Variables/Message section? If not could oyu please give me some help..?
