Welcome to the qcplink Website
VA Linux Systems

qcplink is a small set of command line utilities which interact with the Qualcomm Phones. We're starting with the QCP-2760 model. The utilities will read the configuration/phonebook from the phone and write it to a file and vice versa. Longer term we expect to write light-weight adapters to personal information managers, etc.

Thanks to Seiya Fujii (who identified the CRC algorithm being used) this project is underway once more... (only 23 months after initial start... ;-)

Hey, we're underway! Checkout the latest version of the PROTOCOL document in our CVS repository.
qcplink 0.1 (readonly) is released!


Thank you Seiya Fujii for contributing the final missing piece to enable my moving on with creating a full read/write qcplink. It turns out that the CRC used is the FCS16 algorithm described in Appendix C of the PPP RFC (RFC-1662).
0.1 Release - read only version to enable others to help find CRC algorithm! I'm unable to determine algorithm so far... Help! we need Help! ;-)
first communication 2-way with phone established. Working now on creating 0.1 release which supports reading phone book from phone. Have yet to figure out the checkword calculation. Real close to a CRC but havn't found the polynomial, yet, which works for all known cases (proven that it's not any variant of crc16. Hmmm... could use ideas here... Anyway, until I figure out the CRC we won't be able to write to the phone. I'm anxious and still searching!
First protocol docment versioned - significant data here!
First real look-n-feel for this web. Web under version control.
