[ECOS] Synthetic target serial support

[Nelly Pison]

Hello

I have installed a linux synthetic target (lst) and the synthetic serial 
device with the host side installed.
 I have made a simple test program hello on the lst that  open and print 
characters on the port /dev/ser0 of ecos witch is mapped on /dev/ttyS0 
of linux.

When I start the program: hello --io
it seems to works well but I don't receive any characters from the com 
port corresponding to /dev/ttyS0 and connected to another PC with an 
hyterminal.
I verify that the physical link is OK by writing  a simple program on 
linux: it works, I see the characters on the hyperterminal.
With hello --io the following message is written on the console : 
"Connecting serial device /dev/ser0 to /dev/ttyS0"
This message is printed by the serial host side serial.tcl. I add other 
puts in the tcl for all request the script can execute.
So on the console I see request for:
SYNTH_SERIAL_GETPARAMS
SYNTH_SERIAL_CONFIG

but no request to send characters

Have someone ideas about the problem?
Thanks
