The code shows its clearly related to serial port communications. What the codes mean is related to the protocol the serial device uses. For example, elsewhere you will find code like:
data = 0x70; write(com_port, &data, 1); /* TDO echo off */
data = 0x72; write(com_port, &data, 1); /* auto LEDs off */
data = 0x74; write(com_port, &data, 1); /* ERROR LED off */
data = 0x76; write(com_port, &data, 1); /* DONE LED off */
data = 0x60; write(com_port, &data, 1); /* signals low */
Unless you own whatever serial device they are communicating with, just ignore that code. I haven't looked at the "byte code" player, just the jam player ... https://www.altera.com/download/legacy/jam/dnl-player.jsp Cheers, Dave
