And internet is reached!
I originally tried COM0COM but Windows 11 integrity check blocked that. Older versions of Windows may be more gracious.
So using a 14 day free trial of https://www.serialtool.com/_en/index.php (which also provides Mac & Linux versions) I created a COM to COM pair, COM 5 is paired to COM 6.
Inside FUZIX VTX receives through /dev/modem, so the kernel catches each byte on the interrupt. It still sends keys and pulse-dials by bit-banging PIO B itself. FROG goes entirely through /dev/modem: read to receive, write to send, and the pulse-dial ioctl to dial. It has no PIO code of its own.
A Node.js gateway on COM6 acts as the modem: vtx: vtx3_gateway.js answers vtx’s dialling and connects it over TCP to Telstar (glasstty.com:6502).
frog: frog_gateway.js answers frog’s ATDT frogfind.com:80, then fetches searches and pages on the PC.
The gateway also spaces bytes so the Microbee keeps up. As you can see on the Telstar page a bit occasionally gets dropped.
The entry in ubee512RC:
[fuzix]
--model=p512k
--rom1=HD18.ROM
--hdd1=fuzix81l.hdd-610-4-32
--rtc=1
--piob7=rtc
--title="FUZIX"
--status=+title
--coms=5
--baudrx=1200
--baudtx=75
--datab=8
So UBEE512 FUZIX loads, runs and connects to text based internet.
