serial port block on the command line

[vince]

Hi,

Why this command is blocking on the cygwin shell:

echo "Hello" > /dev/ttyS0

I need to break it with ctrl-c and it gives me the following line:
-bash: echo: write error: Interrupted system call

I don't understand what is going on.

Thanks,

Vince
