Serial Port Echo [30065]

This article applies to:
E-Prime 3.0

E-Prime 1.x

 
Detail
This sample illustrates serial port communications between two E-Prime machines. The sending machine transmits a line of text, with echo to the screen by the receiving machine.

Abstract

This experiment illustrates serial port communications. Two E-Prime machines are connected via the serial port using a null modem cable/adaptor. At runtime, the user is asked to designate whether each machine is acting as sender or receiver (the receiving machine should be launched first).

The sending machine sends a line of text terminated by {ENTER}. Upon receipt of a line of text, the receiving machine echos the string to the display accompanied by a line number. Both processes terminate upon the entering of "end" from the sending machine.

NOTE: This sample requires the use of a null modem cable/adaptor, and potentially a gender adaptor.
