Progress measured in … lines of code :)

Progress is being made. The current tool of choice is Free Pascal. It is by no means a bad product. In fact, it’s a pretty damn great product. But just about every line of code needs to be tweaked, slightly modified, etc. Or so it seemed when porting the Event handling yesterday, which “only” took three hours. Part of this is obviously due to poor design on my part, but I can’t take credit for everything :)

Mike and I have been discussing issues with running the DOS version under Windows 10 Pro (64-bit), hosted by VirtualBox in a FreeDOS 1.2 virtual machine. There seems to be some sort of flow control issue disturbing the transfer of data. I’m hoping Mike finds (and solves) this problem. But, it may come to the fact that the problem is in VirtualBox after all.

While “waiting” for Mike, I’ve been porting some more code, and also began setting up FreeDOS under QEMU instead. It looks promising and feels somewhat surreal to be able to just move around virtual machines, converting them from VirtualBox under Windows 10 to QEMU under Ubuntu Linux 16 on a completely different physical machine, and it “just works”. I came across a fairly good page while configuring networking for QEMU and FreeDOS here:

I will jot down a full description of how I got it working, if I get it working. The next step is to get a “modem emulator over Internet” (i.e. a “virtual modem”) working in this context.
