How can I upload the firmware from a RCM3000 to a PC?

I was given a RCM3000 with unknown code. I would like to upload and compare this code with the release executables. I would also like to gather the System ID Block of this device.

I am connected serially. I can get the System ID by using idblock_report.c but that will overwrite the firmware.

Is there any utility that will read the Rabbit code so it can be saved on a PC?
