Hi folks,

As far as I know, the QExtSerialPort library does not support 28800 baud rate. What is the reason for this?



Kind regards,

Hello,

This baud rate is nonstandard under POSIX (at least on my Linux box
there aren't any related constants in the termios.).
We can add this feature on Windows but I have not idea about that it
should work or not.

Regards,
Mikl�s

Hi,

Ok, I thought it was a standard baud rate. I know that some Windows applications support this baud rate.

Hi Erlend,

I don't want to introduce new enum value such as BAUD28800, but I can
give you an option to do so under windows platform in
QextSerialPort-1.2rc

Then, you can use

port->setBaudRate( (BaudRateType)28800 );

Hi debao, Marten, and Erlend,

just a stupid question:  Is it possible to use 28800 baud in QExtSerialPort?  So far, we tried adding an appropriate enum value, but the device is irresponsive (and unfortunately, we can't change the baud rate... it does work with Putty, though).
If I understand debao's answer correctly:  wouldn't that only work with "-fpermissive" as a compiler option?
Has anybody of you had any success implementing that baud rate?

Sorry for the confused questions.
Best,

Hendrik

Hi,

has anybody succeeded in communicating at 28800 baud?  Is it enough to add the corresponding enum value?


Best,

Hendrik

For what I see in qextserialport.h, you will need to add that value and
recompile qextserialport.

If this is somehow a standard speed, then a wishlist bug to add it upstream
would be great.

Kinds regards, Lisandro.

Hi, 

Custom baudrate can be used in MacOS and Windows in Qesp1.2rc if your system and device support that baudrate. 

   port->setBaudRate((BaudRateType)28800 );


For other platforms such as BSD, as B9600 != 9600, it's not easy to support custom baudrate.

Regards,

Debao

Hi,
thanks, debao and Lisandro.  Turns out -- and it pains me to say that -- we didn't activate hardware flow control (although for some miraculous reason the connection did work without it in PuTTY).

Best regards,

Hendrik
