B4J Question More than one virtual com port at the same time?

[positrom2]

Is it possible to have two virtual com ports open at the same time and transfering data through both (using asyncstreams)?

 

[Erel]

Yes. You should use two AsyncStreams, one for each Serial object.

That's good, thank you.
Apparently, it is not necessary to set the baud rate, they even could be different for both channels.
What makes the difference to a terminal emulator that needs the baud rate to be set?

 

[Erel]

Not sure...

 

[positrom2]

Experimenting I found out:
When you run a terminal emulator (Hterm) prior to the B4J application then the baud rates you have set in Hterm to individual com ports is known to the B4J apllication. I used com3 (9600 baud) and com4 (38400), and other rates. I was wondering why B4J did not need to set the baud rate. So, that was the solution - but who knows why.

It is probably related to the system driver which uses the last settings by default.
