Hi all

I just started using Ethereal and Im amazed with this product.  It is
comparable and in some ways better than the 4 different analyzers that 
I have. Im interested in joining ethereal's developement effort! 

First: Is there a way to capture from the COM/Serial port in a PC? If 
not, has it been discussed? My point is that most telecommunication 
WANs use RS-232/RS-449/V.35/etc using HDLC (lapb, etc) protocol.  This 
way all could be done from a laptop, a Y cable and the proper converter 
if necessary.  (Im not sure of speed limits / limitations of the com 
port and if this makes scence). Even further, would Ethereal work with 
the proper pcmcia/usb/... device like: 
      http://www.sealevel.com/catalog/pcmciab.htm

Second: I see x.25 and ISO 8073 COTP (CCITT/ITU x.224) implemented. 
Has there been any plans to fully implement the complete OSI stack 
(ISO 7498 or ITU x.200).  Is not widely used, but is used...specially 
for FTAM transfers.  Im interested in adding this with time if no one 
is working on it already, or help out.  What do you think? Is it worth 
the effort? The protocols that would need to be added are:

  ISO 8327 Session Protocol ( CCITT / ITU x.225 )
  ISO 8823 Presentation Protocol ( CCITT / ITU x.226 )
  ISO 8650 ACSE( CCITT / ITU x.227 )
  Maybe a subset of FTAM after these


Thanks a lot,
Nilo
