Subject:	Re: Serial port access under expect
X-Accept-Language:	en

Hi Sergey,

I am not sure if I understand you. I am not trying to open
the serial port from two processes simultaneously. I tried
opening the serial port from the bash prompt, which worked
and later, I tried from the expect script which didn't work.
If the expect script is implicitly opening the serial port
twice, then I'm confused. Does the script mentioned below
open the serial port twice?

Regards,

chyrag.
