@tschak it seems very interesting! Imho the fact it is based on an #Esp32 is a plus, because there are already some modems (like the #zimodem ) using the esp32. I have a couple of these, self-built. I hadn't looked at Fujinet in depth yet, but if it uses the tx/rx pins, it may be already compatible with the Zimodem dos serial version. Not sure about the commodore version, btw, it use more pins and hooks to the user port.
I'll definitely try to flash them with Fujinet when I'll have a bit of time! -

My #Amstrad #ppc640 has an old-style 25 pin #rs232 port. Unfortunately yesterday I couldn't source a #db9 to #db25 #serial adapter, so I had to...ehm...improvise 😅
It seems that only Rx, Tx and ground are needed for it to work!

At the end, all will fit in this enclosure (there was an adsl filter inside). I made some holes for the usb and the reset button. The front hole contained two rj11 sockets, I cut the central divisor and obtained a hole the perfect size for the #uart to #rs232 #db9 connector.
Most of my #retrocomputing gear has the old #db25 connector, so I'll need an adapter anyway...

Every time I do some project "for fun" (= not for work) I try to learn something new, in that way i can say the time needed is not wasted.
So, this time I decided to try #wirewrapping . This is a very simple circuit, with no board, so it's a very very simple case, but I tried and I liked it!
Here a photo while connecting the #esp8266 (already flashed with #zimodem and configured to connect to my wifi) with the #UART to #RS232 adapter. -

Hang on... this is bonkers! Booting an IBM PC compatible pc mounting a drive via the #serialport ! Something like the modern computers #netboot !

He uses the #xtide #opensource #bios (https://www.xtideuniversalbios.org/) and a null modem cable to a windows computer. Unfortunately it seems the disk #emulator app is available only for Windows, but I imagine it could be implemented in a #serial #wifi #modem firmware (like #zimodem or #theoldnet 's). Imagine having a #samba share on your #NAS and telling the wifi modem to mount an image on that, then turn on the old pc and boot it from your NAS via WIFI... awesome!!!

I'm going to build a #wifi #serial #modem for my #amstrad PPC640. Something like #theoldnet 's wifi modem, but I'll use #zimodem on an #esp8266 , because it worked ok with my #commodore64 and now I have some experience with it...
The idea is having the esp emulate an #hayes modem on the #UART pins and convert it to rs232 using a #max3232 module.
I also will need to solder a 9 to 25 pin #rs232 adapter, because I absolutely don't remember where mine is (used last time a couple of home moves ago... 😅)

Now it's time for some BBSing... Right now is behaving correctly: no more spurious resets, and I'm using the #C64 to power it, very conveniently.
I'm using it along with the #KungFuFlash to load #CCGMS , so I'm probably driving the #commodore 's 5v line pretty hard... Until now, I only had a couple of missed boots from the KungFuFlash, probably due to an unstable voltage on turn on. Once it boots, btw, it seems pretty stable. The original power brick may not be having the best time of its life...

About the #commodore64 #zimodem #wifi #modem: Troubleshooted, tested and sealed up (i KNOW I will regret this last part, but the enclosure was definitely too janky and I don't have access to a 3D printer to print an adequate enclosure).
Also, I should have DEFINITELY placed the #esp8266 on the edge of the PCB, so I could have made an hole to update the firmware without exploding the whole assembly... 🤷♂️
Lesson learned for the next time... -

I just tried the #zimodem #wifi modem for the #commodore I built. It works, but it was a bumpy ride... at first the #esp8266 was resetting continuously. I thought that the #commodore64 wasn't providing enough current, so I cut the 5v cable and connected to usb power, to no avail: it keeped resetting every now and then. Then i checked with the multimeter and there was a low resistance between the reset pin and ground. Cut that as well, but I got only garbled characters. At the end I noticed a comment in the page I used to download #ccgms 2021 saying it wasn't working on certain modems. They suggested trying the 2017 version and... it worked flawlessly!
