We have a client with a bunch of 3270 terminals, cluster controllers, etc., who would like to add some kind of dialup capability to reach async hosts (or TCP/IP, or X,25 if necessary.) What's a good way to accomplish this? Also, does anyone make a convenient interface from this block-mode side of the world into DBMSs like Oracle or Informix? General SQL queries would be interesting, but the basic application is fill-in-the-blanks and some searching for predefined queries.

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. -- Kevin Kleinfelter @ Dun and Bradstreet Software, Inc (404) 239-2347 {emory,gatech}!nanovx!msa3b!kevin "Don't hold your finger on the button if the motor ain't goin' roundy-roundy."

The 3270 running through a 3174 with an async comm adapter, though, emulates a real VT-100 pretty closely, including getting away from the block-mode orientation. It does well enough. On the other hand, using a 3270 in native mode through a host-based adapter such as the Mitek, or the Interlink I'm using, makes a pretty lousy VT100. Doing anything other than straight line-by-line text entry is a royal pain.
