I am trying to get my cdos program that I use under warp 3 to work under warp 4. I use it to download code through the serial port to an eprom programmer. When run under warp 4 I get the error message &quot;error in cdos open queue function --key dl disabled&quot;. If I reload warp 3 on the same machine, it works just fine. Any suggestions?

Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.
