What is the correct way to include the "-S COM2" command in the config file?

What is the correct way to include the "-S COM2" command in the config file?

Code:

"scan-serial" : "COM2"

Stratum update

The code has been in testing for a while now, and numerous issues have been ironed out. I've been mining with it for a few days in a mixture of regular pools + stratum pools and things seem to working out okay. I've just managed to get it building and working on windows and have created the first binary for people to start testing it. It's still not mature enough for a full release, but at some stage I need people to start testing it so I can sort out issues as they arise.

If you're on linux, and can use git, checkout the stratum branch and build from that.
git pull -a && git checkout stratum

For those on windows, here is a test binary.
http://ck.kolivas.org/apps/cgminer/temp/cgminer.exe

Just drop  it into your existing 2.7.6 directory. It will still read version 2.7.6, but don't let that fool you. For stratum to be active, you need - of course - to mine on one of the 2 pools that currently support it: slush's pool and btcguild . The way I've set up the code, you shouldn't need to do anything special to mine stratum, just use your regular settings (or you can plug in the stratum info directly if you're so inclined). The advantages to the miner should be far far less network communications with less network delays which should also translate into less rejects. Of course the real advantage is to the pools and for the ability to scale to much higher hashrates with the advent of ASICs.

Lots has been written about it here (though it may be rather confusing):
https://bitcointalk.org/index.php?topic=108533.0

EDIT: There is NO proxy support whatsoever for stratum at this stage.

Updated the codebase, and uploaded another windows test binary. It now uses curl for its sockets which allows at least socks proxies to work. http proxies are tricky since you'd need a proxy with special permissions to allow such an arbitrary connection.

Kaerf, what version of linux/architecture are you on?

heh....a ghetto old ubuntu 9.04 32bit intel atom netbook :p

What is the correct way to include the "-S COM2" command in the config file?

Code:

"scan-serial" : "COM2"

or

Code:

"scan-serial" : [ "COM2", "COM3", "COM5" ]

[Jive Turkey]

I started a thread for help building this on Fedora 17 here: https://bitcointalk.org/index.php?topic=114974.0

Any help would be awesome, thanks.

Hmm... can you try the latest git changes to the stratum branch then?

[kaerf]

pulled the latest changes

now debug output keeps repeating

Can you give us the leadup up to the first time you see that message when you have the debugging options --verbose -D -P -T please

[kaerf]

so i didn't go to bed  

found your bug

cgminer.c:4519

   memcpy(work->target, target, 256);

256 should be 32 (or 33?? prob not)

now i can sleep
