Chuck was a man of many accomplishments. He exhibited a multi-faceted persona that friends, family, loved ones and even Chuck would acknowledge, was at times quirky and contradictory.

Chuck was the author of ZMODEM:

a file transfer protocol developed by Chuck Forsberg in 1986, in a project funded by Telenet in order to improve file transfers on their X.25 network. In addition to dramatically improved performance compared to older protocols, ZMODEM also offered restartable transfers, auto-start by the sender, an expanded 32-bit CRC, and control character quoting, allowing it to be used on networks that might "eat" control characters. ZMODEM became extremely popular on bulletin board systems (BBS) in the early 1990s, displacing earlier protocols such as XMODEM and YMODEM.

Ahh, memories of the days of using Procomm Plus on a 1200 baud N81 connection.
