I don't know but I think at least you should be send a carriage return after each instruction.

_CommSendstring("at+cmgf=1" & @CR)

 Sleep(100)
    _CommSendString("at+cmgs=" & "+407xxxxxx" & @CR)

 Sleep(10)
    _CommSendString($message)
    Sleep(100)
    $string = Chr(26) & @CR
_CommSendString($string,1)

 

I don't know what the quotation mark and ampersand are for after the phone number in your code so I omitted them in my example above.

Although serial ports are disappearing, they can still be useful. Here is a COMMs UDF. It provides an easy way to use serial ports without the restrictions and problems some methods have. USB to ser

I haven't tried the COM method but it looks quite good. I posted put my UDF on the forum is because AutoitSteve tried using the COM method and other methods but couldn't send binary data because a byt

Martin, once again thanks a lot for your UDF. I'm trying to use it to get a voltage from a dinamometer with an Arduino (using a 24bits ADC I get up to µv values).

I have created a nice gui to show the volatge recived and translate it to grams and newtons.

The problem is that when I'm on the loop waiting for the value the gui hanges and it doesn't respond to any button pressing (just the minimize button).

This is my last code:

#include <GUIConstants.au3>
#include <WindowsConstants.au3>

This is the last try I have done. I've also tried to create flags as the documentation for breaking functions indicate but I didn't get any better performance.

here there are some of the probes that I have done trying to get a non-flickering update for the values and a good response from the gui (it takes up to 8 seconds to respond after clicking any buton):

        GUICtrlSetData($inputn, Round($Newtons, 3) & " N")
    EndIf
    Sleep(10)
WEnd

I have tried to insert the While inside the function and also to tried to use the parameters of the _Commgetline:

$Arduino = _CommGetLine(@CR, 0, 600)

There is no way of getting a non flickering label update and a fast responding gui.

Any idea? I though that I wasn't as newbie to get stuck in a loop problem like this.

I solved it. Thanks again for the UDF

Hello everybody,

I'm starting using CommMG.au3 and it seems really helpful!

I need though to set data bits to 6 and I'm getting an undefined "!Error: 1" message in AutoIt console.

I tried to set DataBits to 6 in C++ and it's working, so is it a limit of CommMG.au3?

Can it be extended to include 6 DataBits somehow?

Thanks and have a nice day,

Virgus

BTW I have another question: is there available an extension of CommListPorts

where I can get a returntype parameter for Com ports friendly names?

I'll have a look in 2 days (9th March) and get back to you.

Apologies for the delay.

The link on the first page of this thread will get dll version 2.82 which allows for data bits 4,5,6,7 and 8. Previously I had only allowed for 7 or 8 data bits, I suppose because that's all I've ever used.

Hello Martin,

I just found out a small problem with 6bits transmission.

I'm using Parity None, 1 Stop bit, Flow none, RTS & DTR off.

I sent twice a testing pattern like 0x15002A3F; in binary it is:

h15 = b0.101010.1
h00 = b0.000000.1
h2A = b0.010101.1
h3F = b0.111111.1
 

I included the start bit and the stop bit to make it easy to follow the snapshot I attached

(where the first row is the TX output, the second is the TX inverted signal).

So if you have a look at this snapshot I'm getting an extra 0 (in red) is added just before the stop bit (in blue):

h15 = b0.101010.0.1
h00 = b0.000000.0.1
h2A = b0.010101.0.1
h3F = b0.111111.0.1
 

Summarizing 6 data bits transmission is in reality 7 bits data transmission.

I tested from 5 to 8 and everything seems fine on data bits other than 6...

Please have a look and if I might have done something wrong

it just means I need to sleep more at night instead of doing my serial tests ;-)

Cheers,

V.

You are correct Virgus. My apologies for the error. Version 2.83 of the dll corrects this and is ready to download.

Hello Martin,

I'm sorry to write you again (and a bit late) about this issue but with the last release you updated

when I set databits < 7 then I get an error message (once it reported that the serial port was not available

but clearly it was available with 7 or 8 bits).

Could you please give a look to this?

Kind regards,

Virgus

I was steered here since I posted a CommMG question on the general forum.

I'm trying to monitor a serial device that uses 9 bit data - I suppose it's a complete re-architecturing, right?  To make things worse, I need to use a USB dongle version of the serial port.

There is AFAIK no such thing as a 9 data bit serial device to be used on USB or serial port.

At least it's the job of a serial controller (like the 8250 and derivatives) to check the required parity on input, report an error if it's incorrect and produce the valid parity on output.

What's your actual problem exactly? You talked about 9-bit data, now about detecting parity errors. Once the correct settings are found and used, your input will work.

This wonderful site allows debugging and testing regular expressions (many flavors available). An absolute must have in your bookmarks.
Another excellent RegExp tutorial. Don't forget downloading your copy of up-to-date pcretest.exe and pcregrep.exe here

That's why I asked if Parity Error was check-able.  As far as I can tell from looking at CommMG, all errors are lumped together.

My actual problem is monitoring a SEATALK bus, which is a single-wire bi-directional serial line that uses the ninth bit to mark "start of message".  It's collision detection relies on framing errors to some extent, so a universal @ERROR will create problems.

I've already coded a PIC processor to do the job, so I guess I'm giving up with the "easy" solution...

Ha, this weird use! Ask Martin if there is a function in his DLL you can use for that, else look at >this alternative solution.

Of course a dedicated PIC will do the job as well.

Great appreciation to Martin! This UDF saves a lot of my developing time. But it just encountered a problem of using it. While I am using terminal app such as SecureCRT and Hyperterminal to connect to my product, everything is fine. And I am just developing a test program to get access  to my product. Firstly I used the "CommgExample.au3" to see whether if the function is okay. The problem occurs. When I input a command through the example, it received garbled message as a return.(please refer to the attach image) For verifying this issue. I have used a virtual serial port app to simulate a virtual port so that I can make connection between CommgExample.au3 and SecureCRT. I found that the function is okay and the characters are fine. I cannot not figure what's the root cause for this issue. Hope there's someone has the same experience and could point it out for me. Thanks!!

Hi BernyHsu,

Can you tell me the settings for the serial port? The number of data bits, parity etc.

Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.
