Unfortunately I used earlier CVS code. I shall try the latest update a
little later.

Hello Jonathan,
I have tried the latest CVS code.
Now the serial communication works on the i386 platform, as far as I can see.
Communicated both nonblocking and blocking at 115200 baud on port 1.
Downloaded my software with Reedboot, both on a virtual PC in VMware and a real PC and it works fine.
Best regards
Bert-Ola Persson

Does this still happen after all the updates made last Friday in CVS?
And Bert, similarly are you using the current CVS code?

Hello,
I too have confronted with this problem.
It happens always if the serial driver simultaneously transmits
and receives the bytes (for example: usage of an external loopback).

Hello,
I got a problem to make the serial communication to work as it shuld on i386
PC.
I am running the debugg/download stuff on port 0 and other stuff on port 1
The problem is that it seams that when after reciving a few bytes on port 1
it all hang.
Have checked Tx and it works as it shuld, but as soon as I do Rx it
chrashes.
Looks to me like some problems with interrupts DSR calls or something that
is not done in proper way.
The port 1 is configured as nonblocking both TX and RX, 115200,8,1.
Do you have the solution to this problem?
Best Regards
Bert
