Dear Folks, After much deliberation and waiting I finally rxed a C115 and the T1 Cable USB. I am running Backtrack 5 and have compiled the Osmocomm bundles and all executable seem to be present. When i plug om the Jack cable and press the power switch i get this :- ~/osmocom-bb/osmocom-bb/src/host/osmocon# ./osmocon -p /dev/ttyUSB0 -m c123xor ../../target/firmware/board/compal_e88/layer1.compalram.bin got 1 bytes from modem, data looks like: 00 . got 2 bytes from modem, data looks like: 2f 00 /. got 4 bytes from modem, data looks like: 1b f6 02 00 .... got 1 bytes from modem, data looks like: 41 A got 1 bytes from modem, data looks like: 01 . got 1 bytes from modem, data looks like: 40 @ Received PROMPT1 from phone, responding with CMD read_file(../../target/firmware/board/compal_e88/layer1.compalram.bin): file_size=48808, hdr_len=4, dnload_len=48815 got 1 bytes from modem, data looks like: 66 f got 1 bytes from modem, data looks like: 74 t got 1 bytes from modem, data looks like: 6d m got 1 bytes from modem, data looks like: 74 t got 1 bytes from modem, data looks like: 6f o got 1 bytes from modem, data looks like: 6f o got 1 bytes from modem, data looks like: 6c l Received FTMTOOL from phone, ramloader has aborted got 1 bytes from modem, data looks like: 65 e got 1 bytes from modem, data looks like: 72 r got 1 bytes from modem, data looks like: 72 r got 1 bytes from modem, data looks like: 6f o got 1 bytes from modem, data looks like: 72 r got 1 bytes from modem, data looks like: 00 . got 1 bytes from modem, data looks like: 00 .
