I recently posted a Serial ( COM ) Port Console Script. It turns out that port.dll is only able to send a byte out of the serial port once every 15.6ms. Running the exact same loop, but not connecting to the COM port will execute a line of code in less than 1ms.

The device that I am trying to communicate with times out before I can send the entire message.

So, I need to find an alternative to port.dll.

Wisely uses the CreateFile function here http://www.autohotkey.com/forum/viewtopic.php?t=26533&highlight=serial and looking at Micorsoft's website http://msdn2.microsoft.com/en-us/library/aa363858.aspx it seems like it might be able to accomplish what I need.

Wisely's script seems incomplete for my needs. I can see how to open/close a COM port, but I don't see how to send/receive bytes.

Is there anyone out there that is familar with this CreateFile function or have any better ideas on how I can use AHK to send/receive serial port data.

Thanks.

Any luck with this, yet? I too have successfully developed an AHK based tool set around port.dll. I too am frustrated with the extremely slow throughput of the tool.

It IS a flexible tool (giving the dev the latitude to programmatically control ALL of the lines independently), and I haven't yet found something else as robust. Have you had any luck in your search to either speed up port.dll, or find an appropriate alternate?

As info, I have come across ActiveComPort from ActiveXperts. I am chasing this possibility...

Please keep up the search and post any success in this thread. I will reciprocate, if I come up with a viable alternate...

Thanks. L8R.

Hi,
I've lost so much sleep over this tonight...

I think a possible solution could be to use serialterm (no install needed) to display input in a command prompt and CMDret scripts (do a forum search) to capture the prompt display into a variable but I haven't tried it yet.

Hope this helps both of us...
