JTAG Modem Reading Writing

Motorola SBH6121, 6141, 6183, 6190 etc.

@.:hack3r2k:. Was wondering if the JTAG portion of the device supports writing to chips other than the phones most of us are dealing with.

They have a pretty simple program and are able to read and write to a variety of chips with xml format for mapping etc.

Does the current module support that? Or could a separate one be written to do the same>?

Rather give you idea and support instead of keeping another device in my arsenal.
