Wavecom OpenAT FTP serial data

Job: Program Wavecom Fastrack Supreme 20 GPRS modem with OpenAT. Process: The modem is to take in serial input from a current profiler. The current profiler outputs one serial string every 5 seconds. The modem is to store the serial strings into a buffer and FTP the data to a server via GPRS every 1 hour. If the FTP transmission fails, the modem will redial every 10 minutes. Status: We have managed to program the modem with openAT to send the serial data input every 1 hour. But the problem is we noticed that every time the modem managed to ftp only 5840b out of the 20kb data buffer. We tried to tune with this line static wip_channel_t dst_ftp_cx = NULL, dst_data = NULL; wip_setOpts(dst_ftp_cx, WIP_COPT_SND_BUFSIZE, 30000,WIP_COPT_SND_LOWAT,3000, WIP_COPT_END ); by adjusting the below variables but of no use: WIP_COPT_SND_BUFSIZE 30000, 20000, 10000 WIP_COPT_SND_LOWAT 10000, 3000, 500, 100, 0 Using dst_data instead of dst_ftp_cx Another problem is when the modem is FTPing, it cannot take in the serial input so part of the serial data is missing. Now we are stuck and need a programmer to continue from where we left off with the two problem above, and of course the code need to include error handling and ftp retry. Note we require source code. Part of our code refer attachment. The serial input string from the current profiler is below: 16 C811 70802 2008 3 28 12 21 52 3 0 1 2 40 200 100 10 1 0 0 0 2886 17424 0 0 0 0 0 15425 0 0 0 0 61 191 65 193 14 16 18 0 110 192 0 107 1 -1399 -2174 -172 0 0 0 129 131 162 2 -1412 -2378 -294 0 0 0 115 119 136 3 -2078 -1699 -211 0 0 0 115 107 118 4 -1839 -1868 -230 0 0 0 114 118 103 5 -1418 -2299 -333 0 0 0 109 124 104 6 -1778 -1971 -472 0 0 0 79 115 112 7 -1688 -1862 -289 0 0 0 120 95 109 8 -1675 -1995 -358 0 0 0 106 96 115 9 -986 -1709 -324 0 0 0 90 105 102 10 -1246 -1961 -422 0 0 0 87 104 94 11 -1399 -2030 -301 0 0 0 83 95 95 12 -1258 -775 -99 0 0 0 80 95 72 13 -992 -1405 -407 0 0 0 84 94 74 14 -1691 -1885 -484 0 0 0 82 99 83 15 -1603 -1586 -245 0 0 0 80 102 99 16 -1536 -1425 -239 0 0 0 87 91 102 17 -1266 -1690 -232 0 0 0 90 92 100 18 -1814 -1267 -326 0 0 0 65 69 96 19 -1379 -1944 -336 0 0 0 77 67 74 20 -1585 -1822 -495 0 0 0 56 61 54 21 -2084 -1354 -425 0 0 0 82 52 59 22 -1368 -1815 -126 0 0 0 61 63 66 23 -837 -1383 -436 0 0 0 45 58 66 24 -1608 -1715 -397 0 0 0 57 68 49 25 -1775 -1619 -282 0 0 0 47 56 59 26 -1445 -1433 -285 0 0 0 41 39 52 27 -1030 -1451 -256 0 0 0 40 43 46 28 -1248 -1572 -313 0 0 0 51 41 38 29 -1368 -2256 -160 0 0 0 39 43 49 30 -1256 -2065 -164 0 0 0 31 38 46 31 -1615 -2036 -278 0 0 0 29 32 38 32 -1926 -1847 3 0 0 0 50 23 44 33 -1281 -2289 -280 0 0 0 110 66 30 34 -1436 -1745 -343 0 0 0 75 137 32 35 -1763 -1328 -356 0 0 0 15 55 35 36 6009 -2757 -1856 0 0 0 13 13 67 37 -1235 1269 -1493 0 0 0 13 16 120 38 4405 -645 -2062 0 0 0 13 11 78 39 -2618 957 -1234 0 0 0 15 13 22 40 -1753 10311 499 0 0 0 15 14 22
