Hi Cory,

As authors of Flash Magic, hopefully we can help you resolve this problem.

If you can connect to the device using Hyperterminal at a specific speed then there should be no reason Flash Magic cannot do it.

Please send me an Email (aayre@esacademy.com) letting me know the following:

- can you connect at 19200 using Flash Magic?
- what message does Flash Magic give you when you try to connect at 38400?
- are you using the latest version of Flash Magic (version 1.27)? If not give that a try. It also contains some debugging capabilities that I can use to investigate your problem.

As always, Flash Magic support is free to the user.

To duh - the BootROM in the devices does not support any kind of flow control, therefore xon/xoff, rts/cts cannot be used. Instead all bytes received by the device are echoed back, which can be used to determine if reception was correct or not.
There is an upper limit to how fast the device can autobaud to for a specific oscillator frequency of course, and it may be that at 12MHz, 9600 baud is the fastest you can go - measurment at higher speeds generates incorrect results. Using a 20MHz oscillator will allow the device to autobaud even higher. However, the Philips Rx2 and 66x devices also feature the ability to directly program the baud rate to a higher speed, which is much more accurate than trying to measure it. This feature (called high-speed communications in Flash Magic) allows higher baud rates to be used.
