It's not that EMS hardware is required for development, since there are many ways to emulate EMS, it's just that I have no motivation to spend a day or two of my lifetime building something that I will not use myself. That being said I have eyed EMS boards in the past. "True" vintage boards are …

Is there any hope for EMS support in the future for those of us with Turbo XT/esoteric AT machines? A lot of my professional MIDI files I own get very close to, or exceed, the conventional memory limit, despite being 30-40KB in size. EMS support is unlikely to happen since I do not own any EMS …

Just checking if you managed to make the changes? Not yet, no. I did the most challenging part just to prove it's perfectly achievable, and what's left is the easy-but-very-boring details. I still plan to get back to this and close it, but it's pretty far down on my list of priorities at the moment …

Does such a thing exist already in the official PPP specs? Just checking I'm not overlapping with an existing PPP protocol. There exists PPPoE, but that's the inverse of this? There's BCP, but that's for older Ethernet standards, not Ethernet II? I am not familiar with the PPP ecosystem, but BCP ( …

The main issue with full Ethernet-over-modem would be that Ethernet II frames contain all kinds of packets, and afaik that cannot be directly reliably routed over PPP? Due to requirements of configuration etc.? I don't see why you couldn't encapsulate all Ethernet frames. In such scenario, you …

Sounds interesting but... can you tell in a few human words what it is for? Is it, like I assume, some contrived way to make EtherDFS talk to a server that is reachable over a phone line? If so, then why does it need to be EtherDFS-specific? Wouldn't it make sense to rather target a more generic …

Yes, please. Seeing the massive interest in a DOS EtherDFS server (3 people, which easily accounts for some 75% of the total user base) I quickly looked into it. Not as straightforward as I thought: there is still some back-and-forth translation required between int 2Fh and int 21h calls, but …

I'd prefer a EtherDFS-server for OpenWRT, that would be really awesome! I use an old ADSL modem as a low power WiFi-Ethernet bridge + FTP server (USB storage) AFAIK OpenWrt is just Linux, and apparently it has some writable space to install extra stuff. So all you need is to crosscompile ethersrv. …

I have recently made a server implementation for ETHFLOP , the little sister of EtherDFS. Keenerb suggested a similar port for EtherDFS. While at first I rejected the idea as I am not using etherdfs much myself these days, on the afterthought I might actually give it a try, if only for a laugh. I …

Any chance ethersrv could be adapted as an msdos app as well? Technically should be easy, albeit probably not quick.

1. Can it run in a DOS window under Win9x? I doubt it. ETHFLOPD for DOS requires a packet driver to send/receive Ethernet frames. I do not think that Win9x provides such interface. A quick web search tells that there is a thing called WinPKT, but it's only for Win 3.x, apparently. 2. Changing …
