Hi Anamika,
   I have implemented the concept of pseudo device 
drivers for eCos as per Bart Veer's idea of a 
multiplexor, refer to a small discussion on 
"serial device drivers for linux synthethic target!" 
in the archives. 
   This consists of support for SIGIO handling and
connecting with the external multiplexor in eCos
HAL, and multiplexor implementation as well as the
device servers implementation.
   Presently I have implemented serial device drivers
as well as ethernet device drivers for the synthetic
target and got Tristan's port of TCP/IP working in
linux synthetic target.
   If anybody requires the code can contact me at my
mailid, or else I can put the code in the contrib 
section of eCos, provided Bart Veer agrees to it.

That's not what I suggested :)

See http://sourceware.cygnus.com/ml/ecos-discuss/

Search for 'synthetic'.

Hi Mohammed Mansoor

That's a good news. Can you please send the serial
driver as well as ethernet driver to me and if
possible, put it on ecos contrib list.

Thanx
Anamika

Which is correct. There is no serial support implemented for the
synthetic target. 

There has been some work in that direction though (I think). I've been
away for some time and don't recall the details - you should look at
the archive of this list to find details.

[ECOS] Serial Port Opening Problem

[Anamika Gupta]

Hi all

I am facing a problem in opening serial port on Linux
I386 synthetic target. I am using the following call

cyg_io_lookup("/dev/ttyS0",&handle);

It returns -2 which means no such entity.

Can any one help me in identifying this problem.

When I try to open serial port ttyS0 thru open call on
linux, it works.

Is there any specific packages that needs to be
enabled. CYGPKG_IO_SERIAL is already enabled.

Please respond as early as possible.

Thanx in Advance
Anamika
