The Tao of Mac. Apparently Apple ships a nice terminal emulator that complements xterm but for some reason is tagged only a vt100 emulator.

I have followed this guide: And I installed the closed-source Prolific driver (the open source one and the FTDI ones always gave out a AppleUSBCDC error and didn't work both, I suspect it's because this Mac Mini is 64bit?). So now I have both tty.usbserial and cu.usbserial on /dev. I also tried the.plist file mentioning getty, and getty is running but I can't get the terminal to talk to it. Even echoing something to /dev/tty.usbserial does not make it show up on the terminal. Maybe it's because the 19200 entry on /etc/gettytab has 'g ' behing it? Excerpt: 2 std.9600 9600-baud::np:sp#9600: g std.0-baud::np:sp#19200: std.0-baud::np:sp#38400: std.0-baud::np:sp#57600: std.100-baud::np:sp#115200: Here is the.plist file I was using:

Right?:) If the VT100 does not work at all with USB/serial converters, then I guess there's no point but I don't believe so. The terminal in question is this one: Thanks for any help, really wanted to see the dinosaur kicking again! I had a lot of the same problems trying to get a VT220 to work with my Mac. The thing that eventually solved my problem was using a Tripp Lite Keyspan USB to Serial adapter.

Here's a link to the Tripp Lite adapter and the drivers. Canon driver for mac. Previously I had tried two different USB to Serial adapters, one that used the Prolific drivers, and they didn't work.

Make sure to check your cables too. I purchased a null modem cable that turned out to be wired incorrectly or damaged. You can do that with a multimeter. You might have to search for a different pin-out if you're using a DB9 -> DB25 or something like that. Here's a breakdown of what I did and what worked if you're curious.

In 2016 K.C.Lee published a project at that implemented the tricky parts of generating 640x480 pixel resolution text mode VGA video, and interfacing to PC/AT keyboard using a small microcontroller with just few external parts. In his implemenation he went for maximum number of text lines (40) and used up most of the 4KB internal ram of the STM32F030F4 microcontroller. He had not published code for VT100 emulation by Oct 2017, so I branched his code in github to and added the missing pieces. To make the text look better and to reduce memory requirements, I switched to 16 scanline font, reducing the number of text lines to 30. K.C.Lee worked towards producing a module that you could plug into your other projects, but the harware is so simple that you can build it into anything where you need VGA text output just from few components (click on schematics for full size). The keyboard interface has level shifters between 5V keyboard signals, and 3.3V MCU I/O, you can just remove all of the keyboard interface if you dont need it, keep the pull-ups on the I/O pins though.
