Oh this is truly sad news.<p>I first started my online journey with a 300bps Hayes modem and an original 4.77mhz IBM PC, connecting with a service called The Source in 1981.  I soon moved on to Compuserve and then, of course, BBSs.<p>The first protocol I remember using was <i>not</i> Zmodem, but Xmodem, which as I recall, had a really nasty habit of losing its place in the middle of a 2 hour download, forcing you to start completely over.<p>Remember, Compuserve costed $5&#x2F;hr(!), so these disconnect&#x2F;restarts were not only really annoying but quite expensive.<p>Zmodem solved this problem very nicely...it was smart enough to restart downloads at the point of disconnect, and because of this, Chuck was a hero of my youth.<p>Rest wel...NO CARRIER...
