These seem to have been around a while. I got these from the PROTOCOL
document in qcplink (http://qcplink.sourceforge.net/). The protocol is
for the Qualcomm QCP-2760. There are a few differences. The firmware
request returned 53 bytes for the QCP-2760, for my Sanyo it returns 117
bytes. The offlinerequest command (called begin/end update in qcplink)
didn't work as described for qcplink (Packet=0x29, 1 or 2, checksum,
7e). I had to add an extra zero byte after the 1/2 for the Sanyo.
Also, as far as I can tell, the 0x29,2 sequence did not reboot the
qcp-2760, but it does for the sanyo.

The qcplink PROTOCOL guesses this to be "Get Phone Programming
Status". It can be used to check if the phone is ready for updates
after putting the phone into update mode with 0x29/1. I havn't seemed
to need it with the Scp-4900. Here is what qcplink says about it:

I'll try this packet with my phone and see what I get. I see you sent
this command twice and it returned different results each time. What
were you doing each time, what mode where you in?
