Etymology edit

Blend of echo +‎ duplex?

Verb edit

echoplex (third-person singular simple present echoplexes, present participle echoplexing, simple past and past participle echoplexed)

  1. (computing, intransitive) To echo received text characters back to the computer that sent them.
    • 1991, Martin D. Seyer, RS-232 made easy:
      The device that is to echo the characters should be optioned for echoplexing. As indicated, echoplexing is often confused with the duplexes. If a character is typed, such as A, and on the terminal appears AA, the far end is echoplexing while the terminal is optioned for local displaying of the characters while they are typed.
  2. (music, transitive) To apply a tape delay effect on (an instrument).
