Suggestions, anyone? > > /kenw You should check with a company like ACC, Intel, or IBM themselves, as there are boxes out there that will take 3270 and convert into TCP/IP. I do not know the specifics of how exactly this works (someone want to jump in here), but I know that there are several companies who are running our product over TCP/IP out to their IBM through a ACC (or some such) and doing multiple 3270 sessions on their Mac. TCP/Connect supports 3278 models 2,3,4,5 and Brown has a PD version of 3179g emulation that will support one session at a time. As far as I can tell, using a ACC (or whatever) box is just about the standard way of doing what you want. Anyone have any other information to add? -- Kurt Baumann InterCon Systems Corporation 46950 Community Plaza Suite 101-132 Sterling, VA 22170 Phone: 703.450.7117
