RLC4DEMO.EXE is a MS-DOS program that simulates controlling the RLC-4 from its serial port with a computer or serial terminal. Due to the memory limitations of PCs running MS-DOS and the lack of actual controller hardware, some features are not supported. The program sends CW command responses out of the PC speaker, but due to the low resolution of the timer that is used, the CW sounds rough. This problem is not present on the actual controller. Note that the CW can be turned off by entering C045*0 and turned back on with C045*01 as shown in the example below: RLC-4 Reset Software Version 1.47 Copyright (C) Link Communications, Inc. 1995 RE-INITIALIZING...
