Editorial interest 86/100 Selection signal · not a rating of the site

An interactive browser tool synthesizes dial-up modem handshakes, with selectable modem types, line conditions, audio controls, and an annotated spectrogram.

Landing page captured for the 2026-10-28 issue.

For: People curious about modem protocols and dial-up audio
Worth noticing: The site labels handshake phases with references including V.8, V.34, and V.90; it marks post-CONNECT data as approximate.

Field notes

The interface lets visitors vary modem protocol, country, and line condition, then follow the call through a scrub-able spectrogram. It also exposes phase names and standards references, offers WAV files at two sample rates, and includes a Hayes-command console. The page distinguishes its synthesized handshake segments from the approximate audio after CONNECT.
