This updated User's Guide is designed to provide you with information and assistance regarding access to the Scientific Computing Division's computers from your remote location. In addition to the chapters covering specific access gateways such as the PACX port selection device, the UNINET national packet switching network, and the IBM Remote Spooling Communications Subsystem (RSCS), a new chapter on "Special Features" has been added covering new features, products and procedures. This version of the data cammunications guide contains no reference to the MODCOMP system since this computer is being phased out. MODCOMP users are being directed to the IBM batch facility (RSCS). Current MODCOMP users should retain the previous edition of the data ccmmunications manual for reference. Besides correcting errors in the old manual, this manual contains items concerning updates to the RSCS command language, new UNINET PAD parameters, graphics metacode file transmission, asynchronous file transfer features, new telephone numbers, and full screen interactive facilities.
