      What if you want to connect two remote systems via Telebit T2500
      in PEP mode ?  Is this reasonable ?

   SLIP/PEP works fine for FTP, giving ~1000 Bytes/second transfer
   rates, but less than the 1400 Bytes/sec. you can get with a pair of
   PEP modems doing UUCP.

PPP (with compressed headers) gives 1.3-1.5Kb/sec FTP throughput over
a PEP connection, which is getting close to the advertised bandwidth.
I've forgotten whether that's with in-modem compression turned on, but
I suspect not.

   For interactive use, SLIP or not, the v.32 mode of T2500's (and
   others) is probably better, even if the file transfer rate for
   FTP/SLIP/v.32 is <960 Bytes/sec.

...if you're able to maintain a V.32 carrier over a particular call.
There are some places where PEP will get only 3-400 bps for UUCP or
Xmodem, but nobody complains because nothing else will even latch a
carrier because of the rotten lines.  Probably not as much of a
problem in the industrialized world as around the Indian Ocean.
