Can the touch screen be properly operated? (connected with RS232 on the FTF2475A, used PS/2 on MPC5).So we have to test through the following list: We want to determine whether there seem to be any insurmountable difficulties as soon as possible, because there is neither documentation for the application or nor is it known if it conforms to official and therefore emulated APIs. The application running in a DOSEMU box should be able to address the display, the keyboard, the mouse, the touch screen and the network. The project starts with a proof of concept.
So there is obviously no active developing community left to potentially help out. It has been worked on for over 16 years with the last version 1.4.0.1 being released by the Debian project in 2008. Also DOSEMU looks promising for the allegedly most difficult part, the network connection.ĭOSEMU is a really old open source project. This makes it at least theoretically possible for us to solve any upcoming problems on our own. We choose the combination of DOSEMU and Linux because both the emulator as well as the operating system are completely open source. The option of running the application in Windows compatibility mode is eliminated due to the lack of network support for DOS applications.
There are several conceivable solutions for emulating DOS: DOSBOX, VirtualBox, VMware, DOSEMU. As the operating system for this platform IND offers Windows Embedded Standard 7 (WES7) and Debian Linux (Version 7 “Wheezy”) in a special “hardened” version from IND Systems. The old hardware is replaced by an IND FTF2475A industry PC.
TCP/IP network connection with PC/TCP protocol stack (most of the network communication consists of file transfers via FTP) Graphical user interface that is designed for a resolution of 640 x 480 (extrapolated by the current hardware to 800 x 600) How can the client application, part of a client server software architecture, be operated on modern hardware without being changed? Current software Current hardwareġ0.4-inch color TFT, SVGA 800 x 600 pixels There are no spare parts for the old hardware and no drivers to run the OS on newer hardware. The hardware is from 2004, the software running on it was written in 1997 and the operating system MS-DOS 6.22 was released in 1994. The client is a DLOG MPC5 industry PC which is past its prime.
