Hello,

we tried it with an Interlan-NI5210-Card, no success!

Thanks.

In Kermit News number 4, June 1990 Joe R. Doupnik and Christine M. Gianone
writes:

TCP/IP is a very widespread networking method linking machines locally and
around the world.  Kermit does not attempt to speak TCP-ese directly, because
that requires a large specialized body of code in itself.  But Kermit can be
used as the terminal in Telnet connections for some TCP/IP products.  The way
it works is to tell Kermit SET PORT BIOS1, CONNECT.  The TCP/IP product must
provide a connection between that apparent serial port point, BIOS1, and its
own code to send and receive characters across the network.  The general name
for this connection is an Interrupt (INT) 14h interceptor.  On a PC thus
equipped, MS-DOS Kermit can replace the normal Telnet program, and it can also
transfer files over the same connection.

Presently we know of three commercial products supporting this connection: FTP
Software Inc.'s TNGLASS routine running with their kernel software, Interlan's
TCP/IP Gateway for Novell Networks (described above), and Novell's Excelan LAN
WorkPlace for DOS.  The latter provides INT 14h service, 3COM BAPI, and other
interfaces usable by MS-DOS Kermit 3.0.  It is hoped that public domain (or at
least free) TCP/IP packages such as NCSA Telnet will also add INT 14h service
that Kermit can take advantage of.  In the commercial products a small
interface program, such as TNGLASS, is given the name of the remote host and
it starts Kermit when the host responds, for example:

  tnglass hostname -e kermit commands

Then the Kermit commands begin a terminal session with the host.  EXITing
Kermit normally ends the session; just "shelling out to DOS" (Kermit's PUSH or
RUN commands) keeps it alive.
