I had this working fine on 2.0R, but can't for the life of me get it working
on 2.1R despite my researching the docs, searching the mailing list archives,
and reading this group.
All I want to do is be able to dial in and login to my shell -- no ppp or
anything fancy. Internal modem is on com4 (ttyd3/cuaa3) and I *can* talk to
the modem on cuaa3.
When I call in to the modem from a remote modem, the 2 modems successfully
negotiate a connection and report 14400/ARQ, but that's where we get stuck. I
either get a stream of "diamonds" (ascii 4 on the pc) that does *not* seem to
match the signon banner, or nothing. Checking ps on the FBSD side shows getty
is still running on ttyd3 -- no login process has started.
rc.serial is as distributed, but I confess that I don't understand what (if
anything) it does. It appears to have several functions, none of which get
called. Should I be calling one of them somewhere? Perhaps from rc.local?
I have (I believe) locked DTE as I have seen suggested and am out of
ideas. Hopefully, one of you will have some ideas.
Following are relevant details -- probably more that anyone wants, but better
too much than too little :-)
