Read the retro connection guide or download the plain ASCII guide. Includes connection ports, terminal settings, gateway options and testing limits.
SyncTERM official releases are recommended for ANSI artwork and BBS transfers. Choose a release compatible with your operating system.
General SSH/Telnet alternative: official PuTTY 0.85, unmodified and digitally signed by Simon Tatham:
License · SHA-256 checksums · Upstream and newer releases
Choose SSH, bbs.unixtechlab.dev, port 2222. A 32-bit build does not imply Windows 3.1/95 compatibility. PuTTY is a terminal client, not an IRC client.
SyncTERM official platform downloads and source. On Linux, use the official build guidance for your distribution. On macOS, choose a build matching your OS and processor.
ssh -p 2222 [email protected]
Use your BBS password; no Linux root account is needed. Choose 80 columns and ANSI/CP437 when supported.
mIRC for Windows (shareware), WeeChat and Irssi for compatible Unix systems. Get Linux packages through your distribution or follow official build instructions.
Server: irc.unixtechlab.dev · TLS port 6697 · channel #underground. Your IRC account is separate from your BBS account. For clients without TLS, legacy port 6667 is available without encryption.
iPhone/iPad: browser BBS or browser IRC. Classic Mac OS, Apple II, Windows 3.1 and early Linux: see the vintage connection guide. Those machines need OS-compatible client software or a local gateway; modern installers are not labeled as vintage-compatible.
Telephone dial-in is not configured. Hardware-specific clients and adapters still need testing.
All protocols and ports · Accounts and passwords · Activity history
Legacy gateways are live through cPanel and pfSense; public connection checks passed. Prefer encrypted SSH/TLS. Telnet, RLogin and plain IRC carry passwords without encryption.
