Summary: The following is a list of filenames, S numbers, and descriptions for the source code from the November 1989 issue of the “Microsoft Systems Journal” (Vol. 4, No. 6): 1. S12438 UNIX “Emulating the UNIX RS-232 General Serial I/O Interface Under DOS,” by Michael J. Chase, Page 19. This file contains the DOS serial device driver that emulates UNIX serial I/O and demonstration programs for techniques in writing applications that use RS-232 communications. 2. S12439 PRTSC “Exploring Dynamic-Link Libraries with a Simple Screen Capture Utility,” by Kevin P. Welch, Page 61. This utility uses DLLs and keyboard hook functions to capture screen images and copy them to the Windows clipboard. 3. S12440 NEWWAVE “Examining NewWave, Hewlett-Packard’s Graphical Object-Oriented Environment,” by Alan Cobb and Jonathan Weiner, Page 1. This file contains sample applications and scripts demonstrating Hewlett-Packard’s graphical object-oriented environment. 4. S12441 SPYGLASS “SpyGlass: A Utility for Fine Tuning the Pixels in a Graphics Application,” by Kevin P. Welch, Page 75. This utility allows you to see easily how pixels are aligned on a high-resolution monitor in your Windows application and demonstrates graphic device interface (GDI) programming techniques. 5. S12442 IPC2 “Integrating Subsystems and Interprocess Communication in an OS/2 Application,” by Richard Hale Shaw, Page 47. This file demonstrates uses of OS/2 IPC to implement an event-driven, message-based queue that you can use to construct applications whose architecture is similar to the architecture of PM. These files can be found in the Software/Data Library by searching on the keyword, the Q number of this article, or the S number listed above. These files were archived using the PKware file-compression utility.
