Hi Stephen,

     About "Pure DOS TelNet ZMoDem" of October 13:

MS> I tried telnet://guest.sailor.lib.md.us but there is little hope
MS> since 'nix-like `ZMoDem' flavours are different about the Return
MS> Character via ~TelNet~ protocol, if i'm not mistaking...
SH> The ZModem protocol doesn't use a return character.

     I just won't search for the private correspondance i had with Ruurd
Beerstra three years ago but i can attempt to put in words what i recall
about it;  it's quite regrettable i can't point you at some ~WEB~ hosted
records of `FdN_DOS-InterNet' between August and December 2001 though...

     Don't ask me to make any sense out of it, i only tried to collect a
few tips to pass on:  remember, i'm not the SysOp here!  ;->  Well, what
he wrote was about the 'nix origins of his source-code and a natural way
in which it all fell into place...  He commented about a difference with
DOS and i believe it was the Return Character.  I leave the rest to you,
you must figure out where it fits between ~TelNet~ and `ZMoDem'.  Sorry.

SH> If you can't interoperate with an Omen ZModem program, you're doing
SH> something wrong...  and yes, it's probobly the IAC character.

     I interoperate with whatever the authors/SysOps of the time decided
to provided to their DOS BBSers, which is rather limited.  `TNPort' does
address the ~IAC~ problem, it seems, but yet there's more trouble ahead.

     In the good old days of TeleNet (not ~TelNet~), the users were able
to adjust `ZMoDem' (in a similar way as with `Kermit') but most terminal
emulators no longer give access to such long forgotten options and hence
the difficulties encountered by DialUp SoftWare using a ~TelNet~ "shim".

                                                           Salutations,

                                                           Michel Samson
