       Does anybody have a version of SLIP or PPP with SLFP (Serial Line
       Framing Protocol) support in it?  Merit ... does SLFP.
    
    Is SLFP HDLC?  If not, is SLFP documented in a readily-accessible
    place?

SLFP is another way of encapsulating IP on serial lines that is neither SLIP
nor PPP.  It has never been written up in an RFC, and if anything exists
besides the source code, it is probably an internal MIT LCS document (John?
Jerry?).  In any case, it was originally supported in the MIT PCIP, but may
not have been maintained since 1985 or so.  Last summer, Merit asked me for
a Packet Driver "class" for SLFP, and I assigned 15 decimal.  I haven't seen
any drivers yet, nor any patches for existing DOS TCP/IP packages.
