Re: [ECOS] Serial Port Opening Problem

[Mohammed Illyas Mansoor <mansoor at cdotb dot ernet dot in>]

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.
