Serial Port /COM Port UDF

[BatMan22]

@imakidder, I am going to ask a really stupid question and assume you have already checked this out but... You ARE CLOSING "serial monitor" on the Arduino software before you run your autoit script right? Only one singe connection can be made to the serial port as far as I could tell, if my serial monitor was running, my arduino code would not work. You probably already checked this, but had to ask. Also is it possible that your script is not closing down therefore it's causing multiple attempts to connect to your serial port when you run it a second time and erroring out?

AH. Definitely, not a stupid question. Actually I think both of those happened and a few times that is what prevented me from debugging the script. One reason I knew the serial monitor was a problem was because I couldn't see the com port properties under "mode" on CMD. When I closed out of the serial monitor, I could see the properties again. Plus I restarted my computer a few times just to refresh the system.

SOOO, I think I did figure it out. I realized on the link I posted. an error message popped up and  instead of printing the variable "COMPort", I was able to print the actual error code in the message box. Based on the comments Martin placed in the CommMg64.au3 code (Thank you for commenting with much detail!) I learned that the DLL files were not being referenced. In using the function _CommSetDllPath I set the right path and it seems to work fluidly. I think I broke my encoder so I wasn't able to get active data but it worked with the sample code I shared on the previous page!

@BatMan22 Thank you for the insight and the message!

@martin Thank you for some awesome code!

Hi Everyone,
I see the native dll limited to baud 256000. Is there any way to work with baud 300000?

Edited June 17, 2020 by RAMzor

AFAICT the legacy serial (COMx:) support is limited to 256 kbaud and 300 kbaud is a non-standard baudrate.

Checking this UDF I've done a littel refactorizatoin of your code @martin

Hope changes will  be usefully.

Hi Martin,

Thanks for taking the time to redo your ,dll to 64 bit.  I've been switching over some of my scripts with mostly some success.  Here's what I have so far.

Here's what works so far in my scripts in 64 bit mode:
_CommGetVersion(1)
_CommSendString()
_CommGetInputCount()
_CommReadByteArray()
_CommSetPort()
_CommClosePort()
_CommListPorts(0)

Here's what doesn't work:
_CommGetString()

I haven't tried any other functions.

Your .zip file contains Commg64Example.exe; not the .au3 version.  I just got garbage with your .exe.

I took your original 32 bit Commg.au3 & changed it over, but it still returned garbage.   I tried another of my scripts which use _CommGetString() with same results.

I'm using a 64 bit laptop, Windows 7, & testing the scripts as .au3s

Hello Adnadeau,

Apologies for the delay - I rarely visit the Autoit forums now.  Thanks for the feedback.

I will investigate what you have told me and I will correct the files in the zip. It might be a couple of weeks before I get back with something.

Hello Alan,

Hello Martin,

 

I read in old comments about x64-commg.dll, and found this useful hint, but couldn't find, if this problem is already solved. I used the x64-commg.dll for some years for AT-Commands to send SMS by GSM-Modem. Now i tried the same in a x64-AutoIT-application and get just '???' (questionmarks) when executing _CommGetString().

the code is like this:

_CommSendString('AT' & @CR, 1)
sleep(100)
_CommGetString()

So i used _CommGetString for kind of validating the commands before sending the next command. The output comes directly from the USB-GSM-Modem and shows OK or ERROR: xx". Since i'm trying to use the x64-commg.dll (commg.dll V2.79) the output are just '?' in different number, like Alan described in his post.

Exists already a fix for this issue or do i need to use a different _CommMG.au3 ? (I'm using CommMG.au3 V2.90)

 

Best regards and thank you very much,

Jeff

@Danyfirex and I, we are working On ATCmd.au3 UDF. 

WILL BE FINISHED THIS MONTH.

Sounds nice,

Will it also support the x64-compiled AutoIT-Projects ?

If you need some Input, let me know, if it is based on commg.dll and _CommMG.au3. (For the x86-Version, i have really good stable functions)

Attached, you can find selfwritten _SMS.au3 

 

It is not totally commented yet and default country-code for SMS (if phone-number not starting by "00" or "+" is "+49" for germany.

Function-List:

_SIM_CheckModem($e_DebugConsol, $e_DLLFile, $e_COMPort)
_SIM_CheckSIMCard($e_DebugConsol, $e_DLLFile, $e_COMPort)
_SIM_CheckSIMCardPin($e_DebugConsol, $e_DLLFile, $e_COMPort, $e_SIMPin)
_SIM_SMSSend($e_DebugConsol, $e_DLLFile, $e_COMPort, $e_SIMPin, $e_SMSPhoneNo, $e_SMSMsg="", $e_SMSFlash=False, $e_SMSValid=145)

; BASE-Function
_fSIM($e_DebugConsol, $e_DLLFile, $e_ComPort, $e_SIMAction=0, $e_SIMPin="", $e_SMSPhoneNo="", $e_SMSMsg="", $e_SMSFlash=False ,$e_SMSValid=145)

 

Best regards,

Jeff

And please comment or delete the line:

_ArrayDisplay($arrSMSMsg)

Sadfully, i can't edit my former Post yet.. this line was just for testing-purposes yesterday..

 

BR, Jeff

[Danyfirex]

@jeff_poweruser yes it will support x64 compilation.

Hi, the 64 bit dll Works also in 32 bits?

Thanks Jose

[Danyfirex]

@joseLB You can't use  x64 dll in x86 OS arch. 

 

Saludos

[joseLB]

Thanks  @Danyfirex

sorry I mean, using this x64 dll, I can compile in AU3 , 32 bits, or just can compile in au3 x64. The Windows/PC are 64 bits.

 

I´m asking as with the old 32 bits dll, I only could compile in 32 bits. But with the 64, maybe due to other constrains, in some scripts I would have to use 32 bitx compilation.

@joseLB what dll are you referring to?

On a x64 Windows you are able to compile Autoit-Scripts with x64 and x86.. and generally also run both versions. If you compile a Script with x64, the you need to use x64-DLL-files in your script, otherwise for x86-AutoIt-scripts you are using the x86-DLLs (e.g. commg.dll)

In our solution we are using only: kernel32.dll

Thank you Martin for your work on this COMMM64.

I decided to move my question to a new topic as this one is getting rather long.

Hey

I have a question, is it possible to change the baud without closing and reopening the serialport?

It's my firts post in here so HELLO to everyone.

I have read down whole thread, but i cant figure out why my code not working:
 

_CommSwitch(12)
_Comm12()
;ConsoleWrite ("Com12:" & _CommPortConnection() &@CRLF)
_CommSendString("com 12 ok")
_CommSwitch(14)
_Comm14()
;ConsoleWrite ("Com14:" & _CommPortConnection() &@CRLF)
_CommSendString("com 14 ok")
_CommSwitch(12)
;ConsoleWrite ("Com12:" & _CommPortConnection() &@CRLF)
_CommSendString("com 12 ok 2")

_CommClosePort()

Func _Comm12()
    Local $sportSetError

    _CommSetDllPath("C:\Program Files (x86)\AutoIt3\Include\commg.dll")
    _CommSetPort(12, $sportSetError, 38400, 8, 0, 1, 2)

    If $sportSetError <> '' Then
      MsgBox(262144, 'Setport error: ', $sportSetError)
    EndIf
EndFunc


Func _Comm14()
    Local $sportSetError

    _CommSetDllPath("C:\Program Files (x86)\AutoIt3\Include\commg.dll")
    _CommSetPort(14, $sportSetError, 38400, 8, 0, 1, 2)

    If $sportSetError <> '' Then
      MsgBox(262144, 'Setport error: ', $sportSetError)
    EndIf
EndFunc

 The problem is that i get msgbox :

I am runing on Win10 X64 but using 32bit version of dll and CommMG.

Thank You for Your chelp.

Hi all!

I'm use USB to RS485/RS422 Converter from HuMANDATA. This converter can reach baud rates 12Mbps and also support custom baud rate. 
Is it possible to use this device (actually high baud rate) in AutoIt?
