Hey,<div><br></div><div>If I&#39;m not mistaken pl2303 based cables have/had problems handling baudrates above 115200, there was a recent update into the kernel tree, but I&#39;ve never tested it.</div><div><br></div><div>
If you have FTDI based cable try it out, i have one based on FT4232 and it works flawlessly, pl2303 cable gave me a lot of trouble before.</div><div><br></div><div>You can still run osmocom-bb on 115200 cable but I believe it&#39;s not going to be sufficient for sniffing and i think you&#39;ll need to patch the code a bit for 115200 to work (perhaps someone from osmocom can guide here?).</div>

<br>
I&#39;m newbee so excuse me for my very basic question.<br>
I follow all the instructions on <a href="http://srlabs.de/gprs" target="_blank">srlabs.de/gprs</a> given by Karsten<br>
<br>
I have a C123 and a USB / jack 2.5mm - pl2303 based :(<br>
<br>
All steps are fine until I try to programm the compal ram ;)<br>
<br>
./host/osmocon/osmocon -m c123xor -p /dev/ttyUSB0<br>
./target/firmware/board/compal_e88/layer1.compalram.bin<br>
<br>
I get :<br>
<br>
...<br>
<br>
PROMPT1...<br>
...<br>
PROMPT2...<br>
handle_write(): xxxx bytes (xxxx/yyyy)<br>
...<br>
...<br>
handle_write(): xxxx bytes (xxxx/yyyy)<br>
Received 1 byte : xx<br>
Received 1 bytes : yy<br>
...<br>
...<br>
Finally I received e.r.r.o.r (byte by byte)<br>
NOT ACK RECEIVED...<br>
<br>
I can also get (not with the same firmware...) :<br>
<br>
...<br>
PROMPT1...<br>
...<br>
PROMPT2...<br>
handle_write(): xxxx bytes (xxxx/yyyy)<br>
...<br>
...<br>
handle_write(): finished<br>
<br>
and then... nothing...<br>
<br>
I&#39;m going to test the cable, as Philipp has told to Pavel.<br>
I also bought a RS232 / Jack unlocking Motorola (C123) cable and I own a<br>
BlackBox FTDI based USB/RS232 cable... So I&#39;ll test it as soon as I<br>
receive the cable.<br>
<br>
Do you think is a matter of cable, who is supposed to be osmocom<br>
compatible, or a phone issue or even the USB port... ?<br>
<br>
Thank you very much for your help and excuse me again with this kind of<br>
&#39;stupid&#39; question about cable.<br>
I read almost all the subjects, I did a lot of experimentations in a lot<br>
of git branch (master, testing, burst_ind - of course not working with<br>
PL2303 ... + d1cb8ea9b784c7acbafbb2fdcedbdf4655c2f6f5 not working too)<br>
<br>
I think it must work at least in the master branch...<br>
