[comp.protocols.tcp-ip.ibmpc] tn3270 supporting 3270 'extended datastream graphics' ?

jfisher@ISDRES.ISD.USGS.GOV ("FISHER, JAMES R.") (05/23/89)

Does there exist a tn3270 for IBM PCs which supports
'extended datastream graphics' ? I am told this is the native
3270 graphics mode, but I'm only asking this question on
behalf of others.

Thanks in advance.  -jrf
