Hello,

I'm very happy with the serial port communication, just I have some more
question.

When I start the application, I don't know what ports will be used and how
many.
So I have an object array where I add new serial ports depending on the
hardware configuration.

>From this object array, I'm able to send and receive data. I just don't know
how to access to the serial port events (read). Can someone help me in this
matter?

Thanks,
Robi

In my Linux serial port experience, serial port devices are named:

/dev/ttyS0..9 and upwards
/dev/ttyUSB0..9 and upwards depending on what is plugged in USB.

I have done a lot of serial port stuff with Gambas.

I know that trying to open then with the serial port control
will fail is non-exising port. This error can be detected.

It can be possible to open a port as a test to see if it exists, but you
may be changing parameters and stealing chars from an existing
connection.
I've had this happen too....really messes things up.

Hello,

I can see that Gambas can handle the serial ports which is a very good


news


for me.
Can someone tell me how can I get the list of the serial ports of my
computer? I wish to make an autodetect function and only allow to


select


from the working serial ports.

   Hi,
   I'm not sure what your exact requirement is, but if it is persistent naming
   of a hotplug usb to serial adapter then this can be achieved thru udev. I
   have an Aten usb to serial adapter which when plugged may take ttyUSB0 to
   ttyUSB4 depending on what else e.g. wireless modem etc. is plugged in. You
   can create your own udev rule so that when the Aten adapter is plugged a
   symbolic link is created to the appropriate tty. In my case /dev/ttyATEN0 ->
   /dev/ttyUSB0-4.  The  adapter  can  then  be  addressed from Gambas as
   /dev/ttyATEN0.

   Hope this helps,
   Tony.
