good to see there are multiple pepole with interest in SIMtrace.

those are probably all related to the fact that

sure, there are ideas for this. The easiest way is to implement transmit
support in the SIMtrace firmware + host software and use that implementation as
the 'card emulation' part. You can then use any pcsc-lite supported card
reader to actually talk to the card, and write some PC software that passes
and filters or even manipulates the APDUs.

Implementing the reader side inside the SAM7S (on the other UART) will work,
too - but at the expense of having to write your own card reader firmware.
Depending on where you want to go, simply using an existing USB card reader for
the SIM will be the quicker road to success.
