How to use your serial interface:

From a Dos Prompt on a Win machine:

• Write and compile your program. Here are some to try: Getting started Programs
• Open a  command prompt on your Windows machine, set the com port by typing or copying and pasting the following:

mode com1: baud=9600 data=7

• Connect your robot to your computer. I recommend Robert Doerr's ET-18 Robot Serial Interface. You can obtain a kit from Robert for about $30.00 plus shipping and handling. Click on his name above to e-mail him and ask for one.
• Ready the Hero-1 robot for terminal receive by entering 3A on the keypad.
• Transfer the program to the robot by entering from the command prompt:

copy xxxx.s19 aux       whereas xxxx = your filename.  This name cannot be longer than 8 characters.

• (note: aux is the same as com1. Some versions of Win 95/98 don't understand com1 or com2 devices.)
• The robot should say "Ready" when the transfer is complete. If not, check the baud rate setting on the robot serial interface.
