Two ways: 1) put the IBM asynch cards in the 3174 cluster controllers;
   these can be configured for dial-out as well as dial-in. I think that
   each card provides 8 serial ports, and you'll get microcode to hack an
   emulation out of a 3270 (but you'll have to press an attention key
   anytime you want data sent).  2) Put a Mitek box on the host, and it
   will let you connect via TCP/IP to Unix; it too provides an asynch
   terminal emulation for a 3270.

Depending on the number of terminals, it may be cheaper to buy $300 terminals
for each user. Plus, the 3270 is NEVER going to provide a good asynch terminal,
because it is inherently a block mode terminal.
