My recommendation is to use jnos386g.exe (80386) or jnos086g.exe (8086) as
a replacement for the nos11* compiles. This versions are derived
from jnos110g and have all the nice servers from nos11* 
and a nntpserver included (jnos386g only). There is also a PASV mode
ftp compiled in. JNOS is very well supported by the JNOS group at 
hydra.carleton.ca. 

Note that the syntax of some commands in jnos slightly differs from
the nos11* syntax! (see the jnos.nos example). I add the JNOS Online-help
files 'cmdshlp2.zip' to this distribution. Unpack this archive 
to the directory nos/help. Type 'help <command> to get help from
a specific command.

Note that my example of autoexec.nos starts jnos in 
a dosbox under win3.11. The ethernetadapter I'm using
is a ne2000 clone and the NDIS3 protocol is intalled.
Dan Lanciani's ndis3pkt.386 which is loaded over NDIS
gives me multiplexed interrupt for all Dos sessions.
So we don't need any realmode driver, exept for the slipdriver.
