:
Many IBM mainframe sites have terminal servers that provide access to the
mainframe. Users dial up the terminal server and then make a tn3270
connection from the terminal server to the mainframe. The terminal server
translates between (say) VT100 and IBM 3270.
When you are on site, rather than dialing up from outside, you can (in
theory) make a telnet connection to the terminal server and a tn3270
connection from there to the mainframe and get the same effect. This
depends on the terminal servers being configured to allow telnet access.
You can do the same thing with any UNIX host on the local network replacing
the terminal server: telnet from K95 to the UNIX host and from there tn3270
to the mainframe. Ditto for any other host that has a Telnet server and
tn3270 client.
I hope we will have tn3270 built into K95 some day before the need for it
entirely disappears, but as Jeff says, our list is very long and tn3270
implementation is quite a big deal.
