S3cret91 Posted January 4, 2019 Share Posted January 4, 2019 Hi, can the baudrate somehow be increased? I tried 2,000,000 and other values but they do not work, highest seems to be 256,000. But higher ones like 2,000,000 work fine in visual studio and processing. The connection itself is being established but the _CommAPI_ReceiveString method will time out.

Arses Posted March 27, 2019 Share Posted March 27, 2019 Hi, yes you can! File: CommUtilities.au3 Func: _CommAPI_CreateModeString String: Case 11 To 256000 Change 256000 value to 3000000 Its works! But no more 3000000 baud. Link to comment Share on other sites More sharing options...
Trax Posted February 14, 2020 Share Posted February 14, 2020 (edited) So far this works with the latest Windows 10 (1909) Does anyone know if this UDF supports reading a Comport that is already open by another program? I have seen references to it on the internet when you can eavesdrop on a serial port that is already open. Is this doable with this UDF? Anther thing I am struggling with are the return codes. I call _CommAPI_OpenCOMPort() on a non-existent port and it returns a -1 which, according to the documentation, then requires a call to _WinAPI_GetLastError() which in turn return 2 which is invalid return type. In looking through the return codes I don't see any that would signify things like "port does not exist", "port already opened" or things like that. Aren't those errors available?

That happed probably because you clicked on "Save link as", so the browser save the html page, not the file. Link to comment Share on other sites More sharing options...

manutz88 Posted June 4, 2021 Share Posted June 4, 2021 According to what I read in the "Features" session, this UDF is capable of LPT ports management. "Possibility of parallel communication (parallel port, LPT port)" Can someone give an example...I cannot figure it out how can i connect on a LPT port Thank you so much!

Danyfirex Posted June 4, 2021 Share Posted June 4, 2021 Hello @manutz88 It seems to be is not implemented. You would need to modify _CommAPI_CreateModeString function to support LPT string.

JavierMdq Posted March 19, 2023 Share Posted March 19, 2023 Hello. Does anyone know why, in the _CommAPI_GetCOMPorts function, in the following line of code: Local $oItems = $oWMIService.ExecQuery("SELECT * FROM Win32_PnPEntity WHERE Name LIKE '%(COM%)'", "WQL", 48) the number 48 = 16 (Return Immediately) + 32 (ForwardOnly) is passed as a parameter? If I pass 0, the call doesn't return until the query completes (I think is more helpfull), and I can also get the number of items returned without ForwardOnly ($oItems.Count exists and doesn't return an error like passing the Forward Only parameter does). I attached my modified version (I change function name so I can use both functions) for anyone interested. The differences: autostart of WMI service if not running detection of LPT and COM ports can filter out LPT ports can filter out ports without port number can return array of ports detected as port numbers, port names (COMx/LPTx), or bi-dimensional array with port number, port type (COM or LPT), hardware ID, port description _CommAPI_GetPorts.au3 Link to comment Share on other sites More sharing options...
Chuckero Posted June 16, 2023 Share Posted June 16, 2023 Hello, Is there a way to work with events instead of pulling the serial port? So every time one byte arrives a function can receive that byte, this way I can implement a circular buffer for a more advanced communication protocol.

I don't use this but looking at the code, all you have to do is to code your own events on reception. You'd have to pull from _CommAPI_ReceiveData() every so often ( with AdLib or timer or your imagination ) and trigger your event for the rest of the script. The data will be there but you'll have to read to be aware of the data been there. Should not be a big deal.

So, there is no way to work with events, I have to work with pulling the serial port at a high frequency, or at least, high enough to not let the input buffer fill up.

You can always fork ( look in my signature for examples ). That way, one script as the serial com handler and the other, the GUI that receives the data from the other via IPC. Therefore, even thought AutoIt is slow to handle so may things in a single thread, with this approach you'd have as many threads/cores working for you as you feel you need to have, to make it in time to handle anything. Or most anything, again, gotta be creative Follow the link to my code contribution ( and other things too ). FAQ - Please Read Before Posting.
