Hi all,

I have two questions as in the following :


(1)    I do not understand the meaning of

                    in_xmap(ppp,c)

,which is given as

/usr/src/linux-2.2.12/drivers/net/encod.c:#define in_xmap(ppp,c)
(ppp->xm
it_async_map[(c) >> 5] & (1 << ((c) & 0x1f)))

This definition  is also given in ppp.c file.    The typical usage of
the in_xmap(ppp,c) is as follows:

/usr/src/linux-2.2.12/drivers/net/encod.c:              if (in_xmap(ppp,

c) || (
islcp && c < 0x20)) {

 It would be appreciated if I am informed of  the
meaning/concept/reference of "
in_xamp(ppp,c) ".



(2)   In addition, I am interested in PPP for ppp-over-atm and/or
ppp-over-ethernet in PC window 98.  Can anybody
tell me on how to find
   (a)  the public-domain  source   ?
   (b)  information on the commercial product ?

Regards.
