No obvious way to send input to a Cascade Compatible driver (such as the CIF Driver).
When a Cascade Compatible driver runs, it should not return to the prompt, nor offer any form of interactive input. It is designed to run essentially as a daemon, taking requests from user-written client programs and interfacing continuously with the card.
Each Cascade Compatible driver archive includes a program called lsend that allows you to send configuration commands interactively to the driver while it runs. Any command that can be placed into the configuration file can be typed interactively to lsend. To use lsend:
[sh]$ lsend driver_name
You should now get a prompt, at which you can type any configuration command, complete with parentheses.
In production, it would be best not to use lsend, but rather to either write your own client in C, use the Cascade DataHub and/or write a client using Gamma.
For more details, consult the manual for the specific Cascade Compatible driver (CIF Driver).
