Serial Ports are not working

Serial receive on serial ports is broken (????).

I have the following lines in my config

"Com1" = "/dev/ttsS0"
"Com2" = "/dev/ttsS1"

Transmit is OK! but receive is not working.
I am not familiar with linux serial programming, but I think that there
is problem is serial.c or async.c. 

Looking at serial.c (and trying to print some messages in various points
of code) it seems that serial_get_poll_events() function is working but
later in async.c the receive event is lost. Unfortunately I dont have
knowledge of internals of linux events to solve the problem.
