There was a transition during the 90s where the DB25s were phased out and replaced with DE9s. Computers became more commonplace and popular, and they also became smaller, so the bulky 25-pin port fell out of favor.
- hulitu 4y agoThe bulky 25 pin fell out of favor because some of its pins function was implemented in SW (new SW appeared which used SW flow control).
- II2II 4y agoHardware flow control was retained with DE-9. The lines that were dropped included an entire secondary communications channel and timing signals, the sorts of features that I doubt saw much use in personal computers in the 1980's (when it was mostly used for things like modems and printers) and would see even less use today (when it seems to be mostly used for diagnostics ports).
