Thanks For putting this together Gradius. For those who can't find the "RS232 to TTL" board locally, there are plenty of them on ebay, just search for "RS232 -usb" or "MAX232" Also, make sure its rated for 5v, then you can power it from your PSU. And if anyone can find the little jumper cables on ebay too, please post a link. In Windows XP SP3, the HyperTerminal is in "C:\Program Files\Windows NT\hypertrm.exe"
