   You need getty(8) or /usr/ports/comms/mgetty+sendfax. Please read
   
 http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/dialup.html
 http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/userppp.html

  This shows how to connect to some other ISP with ppp. I need to setup MY 
  machine
  to accept INCOMING PPP, and can't find any doc (though I could have 
  overlooked it).
  Pointers to setup of incoming ppp dialin greatly appreciated.

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/userppp.html

Assuming you're using userppp rather than pppd.  The above is a useful
outline, but for some detail I include the dialup configuration from an
old server here.  Note this was for FreeBSD 2.2.6 and a few things have
changed, like the names of ttydX and cuaaX, but maybe it'll help.

/etc/ttys:

 Ian

I set my sendmail to issue that in response to some spammer foolishness about
opt-in and opt-out and their bogus assertion regarding opting-out of their
mailings. What is more to the point is that your message was rejected because
your connecting domain, lnk.telstra.net was entered into my local, private,
set-and-forget blocklist a long time ago for sending spam.

Thank you for attempting to reply to my question, though.
[The telstra.net entry in my blocklist has also been removed].


The pointers sent regarding incoming PPP have veen very useful.
The last time I set this up I was on a BSDI system, and the protocol was 
handled by
pppd, not the ppp client. I kept looking for pppd related info, and didn't look 
at
the (newer) ppp client pages.

man getty, put the right line in inittab and gettytab, and configure your 
modem to answer calls - you will get terminal access.


other metod - use ppp to make IP connection to modem on password.


second might me less efficient in case of slow modem, remote work will be 
slower

They point you to the right direction. To accept incoming calls via
phone line, install mgetty+sendfax, and edit config files
in /usr/local/etc/mgetty+sendfax, especially dialin.conf and
login.conf. Besides that, read pppd(8) thoroughly.
