Sure -- it's called tn3270.

You'll need to have a protocol converter somewhere at the other site
which knows tn3270 protocol.  Give OpenConnect Systems, Inc, a call at
+1 214 484-5200 or drop them a line at support@oc.com.

1) Your 3270 based host/mainframe must understand TCP/IP.  This can be
	accomplished in many ways.  A common approach is to channel attach
	a front end processor that connects a TCP/IP data stream to a
	3270 data stream.

2) You need a PC/MAC/Workstation/whatever application to emulate a 327X
	terminal.  A winsock based 3270 program is available from
	ftp.ccs.queensu.ca:pub/msdos/tcpip/qws3270.zip.  The Chameleon
	327X emulator is a good one as well.  You have to pay quite a
	bit for it though... :)


Hope this helps...

The other way (and the one we usually use since it is usually MUCH
cheaper) is to install a small Sun - SS5 usually nowadays - very cheap -
with an HSI or Token ring card depending on free connections on the
FEP and SNA 3270/RJE software. The connection between the Sun and FEP
is SDLC (for the serial line) or LLC (?) for the Token ring. The Sun
then provides a TN3270 server to which you can attach your favorite PC
3270 software which supports TN3270.

This works VERY well.
