Tutorial: Telnet to a BBS using a terminal program in the Hatari emulator

A screenshot of ANSIterm running in the Hatari emulator.

I’ve written in the past about my adventures telnetting to BBSes from terminal programs running inside the Hatari emulator. I’ve made some changes in my process and I thought it would be good to explain everything, step-by-step. It’s not for the novice, but it is rewarding.

Using high res on my Atari ST with the CosmosEx and a wire

This image shows a CosmosEx screencast of an Atari Mega STe in high resolution.

Throughout my Atari ST-owning life, I have only ever owned Atari’s color monitor, the SC1224. It can display two of the ST’s video modes: low resolution (320×200, 16 colors) and medium resolution (640×200, 4 colors).

The Atari also had a 640×400 high resolution mode, but it required a different monochrome monitor.

I never had a mono monitor, but recently I came across some high-res software I wanted to test. What to do?

Modding an iPod 3G to use a CompactFlash card

This year my family was planning to take a trip to South America. As we prepared, I was struck by the idea of fixing up my old iPod 3G so that the kids could use it to listen to music while we traveled.

I’m talking about my 15-year old touch-wheel iPod 3G. The battery has long been shot, and I have had trouble with the hard drive over the years.

I found quite a few tutorials online about how to install a new battery, as well as some which explained how to replace the hard drive with a CompactFlash card. Sweet! Sounded like a great way to soup up some old hardware: better battery life, more durability, and lighter-weight.

Telnet to a BBS using a PC terminal program within the DOSBox emulator

A few months ago I wrote about my experiences trying to telnet in to Atari BBSes using an emulated Atari on my Mac.

Basically the solution boiled down to this: Use tcpser4j to change a telnet connection to a serial connection, use socat to pipe that serial connection to a file, and set the Hatari emulator to use that file as a virtual RS232 device. After those steps, I could run my favorite old Atari ST terminal programs like ANSIterm and Freeze Dried Terminal.

Recently I decided I wanted to do the same thing with a DOS emulator like DOSBox — but for different reasons.

Telnet to a BBS using a terminal program in the Hatari emulator

UPDATE (2020-09-03): In the years since I wrote this blog post, I have found some ways to improve this process. Please read my new tutorial on how to telnet to a BBS using a terminal inside the Hatari emulator.

When I was a kid calling BBSes, I used an Atari ST computer. But I seldom used the ST’s native terminal mode: VT-52.

The reason is simple. Atari’s VT-52 mode offered only 4 colors in medium resolution. PC clones, however had an 80×25 mode with 16 colors and special graphics characters. This was known as ANSI.

PC BBSes with their colorful ANSI graphics were dominant in the early to mid-1990s, while Atari BBSes were dying out. Since I was mostly calling PC boards in those days, I used a terminal program called “ANSIterm” which could display ANSI graphics on the Atari ST using special tricks.

I’ve been thinking about Space Empire Elite, one of the first BBS door games I ever played. SEE was written for Atari ST BBSes. It supported VT-52 as well as plain ASCII, but not ANSI. But I had never seen it in VT-52. How would it have looked? I was curious.
