Sigh ... Those devices *do* work with the mTCP Telnet. You have to set echoing and get the carriage return/line feed/new line character combination correct. Rich at the TheOldNet provides the specific settings with his devices using the https://github.com/martin-ger/esp_slip_router firmware. He …

I would have never disabled the cache, and thus have never figured this out. So clearly the timing loop in EPPPD is broken if it is speed dependent. But that doesn't make sense to me either, because any reasonably written serial code will ensure the UART buffer has space before trying to send …

I haven't done this in ages so when I saw thread I figured it was a good time to verify that it still works. The guide at medium.com used my original mTCP instructions. Since that time the only change is probably the noauth option, which you figured out. I also had to set nocrtscts on my Linux to …

Er, for the record, people can make their own decision about the forks of Open Watcom later than 1.9. Its more accurate to say that I'm happy with Open Watcom 1.9 for my work.

That page is a joke, right? I read the code they posted but I can't tell if they really wrote something in assembly language that works or if the data statements are just for show. Edit: Definitely a joke. Read the BASIC code they have posted. 😀

Just for giggles I registered a new domain name, setup dynamic DNS, and pointed it at a PCjr running a test version of the mTCP web server. Well, that was 3+ weeks ago. Right now is has been running 577 hours straight. It's not a terribly busy server, but once in a while it gets a burst of activity; …

The packet driver is a TSR - when you load it, it stays running. Many of the Crynwr derived ones can be unloaded with the -u option. mTCP programs do a "handshake" with the packet driver when they load, and they "un-handshake" when they exit. Assuming the programs start and stop fully, the packet …

Some things to try: Can you ping using a human readable name, such as vogons.org? If so, then DNS is working. If not, try using a direct IP address and deal with DNS later.

mTCP author here ... Just to be very clear, mTCP doesn't care if your card is full duplex or half duplex. But it is totally dependent on the packet driver. To send a packet mTCP uses a software interrupt, which in DOS is just a fancy function call to something outside of your program. To receive a …

It's unlikely that any manufacturer of a router or NAS is going to include a proprietary protocol like EtherDFS, even if it is open source. It's just too much of a headache for them to support in the long run. NFS, SMB, and FTP are all well established standards. I'd look more to that "Swiss Army …

On 16 bit machines it is not feasible. Even if all of the current library support was available right now, it would be too slow and it's a moving target that would be obsolete in 3 years. The best options are: Start equipping old machines with Raspberry Pi Zeros to serve as crypto coprocessors. (Pi …

I like the idea of ATA over Ethernet - it is simple and it is a standard, although rarely used now. From the DOS side it would look like a RAM disk device driver; just another block storage device. It would not be usable as a true network drive, as it would not support sharing across multiple …

I wouldn't use TCP/IP for something like this - it's too heavy. UDP is a much simpler protocol that will work fine on a local network, and it is simple enough to redo it in assembly. (I'm planning my own shared drive letter device driver for mTCP that will use UDP or ATA over Ethernet to a Linux …

If you just need to move files on occasion and the machine can run locally from those files, then you want to do a file copy. FTP is the lightest, most direct way to do that. Shared drive letters make more sense when the machine doesn't have local storage (a hard drive), that local storage is …

Interesting .. I'm confused on the half duplex part, as I would expect the card to support full duplex. VLB cards were not cheap, and PCNet32 derived cards should support full duplex. The BNC and RJ-45 results should always be the same, as it is just a matter of the transceiver that is being used. …

That is indeed correct - the DA15 is more commonly known as an AUI port, and it is for an external transceiver. This picture shows an AUI port in use with a CentreCom 210 transceiver, giving the card (a WD 8003) the ability to connect to a modern twisted pair Ethernet switch: https://www.brutman.com …
