    Control XMPCR/XMDirect with iPad?

    I know that the XMPCR is a USB-to-Serial interface, and the XMDirect is a serial interface. I know that serial communication is possible over the dock connector on jailbroken iPhones/iPod Touches/iPads. So can we get an app that we can hook our XM tuners into that controls them? Should be as simple as programming the GUI to execute .shell scripts, but I don't know for sure...

    I can get a page with the commands if we need it. I would really like to have this, but I have no clue how to do serial commands in Terminal, let alone write an app for an iPad...

    A friend of mine wrote a java program that controls the old xm direct via usb-serial commands. It's open source. Your best bet would be to connect that to a Sheeva plug or better yet, an igep and have it serve up a web page that tells the java prog to change channels, etc.

    Then, pull up the page on the ipad and control away.

    Current findings:

    The XMPCR uses TTL style connections before the FTDI serial-to-USB chip inside.
    Source: http://xmfan.net/viewtopic.php?p=227543
    https://xmfan.com/viewtopic.php?t=29942

    Also the iPad uses TTL through the dock connector, so I don't think I'll need a MAX232 to do anything. I'll find that source later.

    This may be easier than I thought... *fingers crossed*

    Got my Mac mini almost back up and running. But I also got more info on the XMPCR.

    This is what is printed on the FTDI chip:
    Ft232am
    0336

    Data sheet: http://www.freeflashstuff.net/CarPC/ft232am.pdf

    These solder points are hella small!

    Photos of the FTDI chip:

    I guess my mac is too old to do anything with that code. I try to open it and it tells me arc is invalid = ppc valid_arch = i386...
