  Troubleshooting PPP problems? 
 The Question is:
 
config of ppp.  i recently took one of our older
alphas home for support.  read all the stuff
and help files on pppd.  i installed the
drivers with the sysman utility.  i connected
via modem to a server at the office, but as
soon as i press return to get username i get
the following:
error reading from tta0:
sys-f-partescape, partial escape
pppd-f-abort, fatal error encountered, operation terminated.
 
i reread all the manuals. pppd show port, says:
port not configured, showing defaults.
 
i cannot find anything on what i am supposed to
configure.  i have used pppd set for some of the
parameters, still get port not configured.
 
one good thing from all this.  i've spent years
developing for VMS and usually can find what i
need in the docs.  this time i'm online searching
and i found this faq page and this wizards page.
in going through both looking at all the ppp and
ucx stuff i saw other interesting topics and
many have helped me get more usage out of my VMS
systems in the last two days.  way cool, i like
this online archive help stuff.
 
 
 The Answer is:
 
  The specific model of Alpha system and serial line will be
  of interest here, as is the baud rate.
 
  It appears that a character was lost and the terminal driver
  returned an error on the communications port used for PPP.
  The utility should not fail when that happens, this would
  appear to be a bug.  The maintainer of PPP is surprised that
  failing as the line is supposed to be set to pasthru.
 
  You will want to ensure the port on ttao has the alternate
  typeahead buffer enabled before trying to make a connection.
  Certain systems such as the DEC 3000 series and the console
  lines on certain other systems are known to have baud rate
  limitations -- faster baud rates overwhelm the capabilities
  of the underlying hardwere, as the hardware was designed for
  an interactive user and not as a network connection.
 
  To verify the underlying hardware path operates as expected,
  attempt to make a dialup connection via SET HOST/DTE.
