Please contact your local Intel Sale!! Office or autho-rized distributer for product order codes.
LICENSING
Before iRMX I software will be shipped, a customer must sign (or have already signed) Intel's Software License Agreement (SLA). Once the SLA is Signed, the customer is licensed to use tne iRMX software for application development. Customers who want to
"incorporate" portions of the iRMX I Object Code in an application, will have to sign an Incorporation Li-cense which 'clearly spells out the terms and condi-tions under which incorporacondi-tions can be made. Con-tact your local Intel office for more information and for appropriate licensing.

The Human Interface allows multiple users to effectively 'develop applications. maintain files. run programs. and communicate with the operating system. It consists of a set of system calls. a set of commands. and a Command Line Interpreter. Commands are available for file management. device management. and system status. The Command Line Interpreter is a sophisticated tool for program development and system design. Its fe,atures include dynamic logon. full line editing. user extensions. and support for background jobs. In addition. the Command Line Interpreter may be replaced for special applications. For example. a Computer Aided Tomography (CAT) scanner controlled by iRMX II software can use a custom Command Line Interpreter to allow the operator to direct the movcment of the scanner.
