I am aiming to run a cdrom stepper motor and have downloaded some code written for a picaxe 28 and a L293d driver. The program is "designed to wait until it detects a serial input on input 0 (pin 17) in the form of three bytes: The first is a qualifier – 85 uniquely identifies this stepper motor – the second is the number of steps – 0-255, and the third is the speed – 0-127 is backwards, 128-255 is forwards" Could anyone tell me how to write the serout command to deliver this input? Thanks loads. Steve
