Description

Hi

Unfortunately the selectable baudrates at serial communication in Gambas is limited to a fixed set of baudrates including 50, 75, 110, 134,5, 150, 200, 300, 600, 1200, 1800, 2400, 4800, 9600, 19200 ....etc.

Other programming languages like Python are supporting custom baudrates, which are indeed needed for certain purposes. As I also need this and in order to catch up with Python and up-to-date Linux capabilities I kindly request a modernisation of the gb.net component. 

Although I am not a C-programmer, the required modification appears to be achievable without a big efforts. According to a suggestion of a c-programmer I provide following supporting references:
https://www.cmrr.umn.edu/~strupp/serial.html
https://gist.github.com/lategoodbye/f2d76134aa6c404cd92c

I can imagine that the struct requires modifications and the Bother-flag needs to be used.

It would be my pleasure to test any related upgrade. I have the required experiences, according serial interfaces, cabling, an RS232 tester and oscilloscope.

Best regards
