Hi.
Iam looking for a way of upgrading my Magician with a serial port, so I can use it with a proper line modem. I know there are several SDIO modems around, but too expensive. Does the CPU havve such a UART or something that I could use with a level converter??

Hi folks,
this is for everyone who can not get a serial cable or who is unable to wait for a cable after ordering it.
I modified my USB cradle and added a serial cable to it.
My cradle is a T-Mobile MDA 2 german one,
but I think others are the same.
Here is a small, pictured, description how I did it.

Now You can read Your roms to sd or do all other serial things.
Be sure that You are able to do the soldering things. If not better keep Your hands out of it.
Anyone know of a micro USB to RS232 Serial adapter?
or for that matter if the Epic can be used in USB Host mode?
My goal, is the be able to use my Epic 4G to run a terminal link to some control boards using ZiLog Z8F processors, I work a job as a field technician on energy management controls. Currently I lug a net book around to flash and terminal into the controls.
If I could do the same without having to drag my net book with the rest of my tools, that would be incredibly awesome for me, I'm always trying to find ways to minimalism the amount of gear I have to carry from my truck to the boiler room.
Thanks
The only thing I have seen that comes close to what you are asking is this thread in the dev section: http://forum.xda-developers.com/showthread.php?t=833373
I dont have any information other than the link, but thought I would at least point it out.
Thanks, at least now I know where to ask questions and pick peoples brains!
If you could find the appropriate cord and drive it from your epic.
I used this back in the day (not from a phone) when I lacked a RS232 port on my devices...
I have seen adapters that would likely drop the usb to micro easily enough but.. thats the least of the difficulty

really not sure if it could even make this work from an epic, lacking any readily available drivers though.

If you can relax your requirement for USB, then use IOGear RS-232 Bluetooth Serial Adapter (model GBS301). I use this along with the app BlueTerm on the market. Works for all of my RS232 needs.

Might be worth a shot. I didn't see anything looking quick, but I know they have lots of different options and if all else fails custom build components as well.
A USB serial adapter won't work with the stock rom (or any custom rom not implementing usb host/otg).
In theory, it's possible to repurpose the usb port's pins as gnd, txd, rxd, and a resistor of specific value that tells the phone to electrically route their signals to pins on the SOC chip with txd & rxd functions at nonstandard voltage levels, but I'm not aware of anyone who's literally gotten it to work on the Epic, yet.
Note that serial via this method has *nothing* to do with usb; it's just temporarily repurposing the pins & connector for serial use.

I would normally coordinate this with some of the devs on IRC but I don't have access to it at the moment.
Obviously a lot of work is going into a Gingerbread kernel bringup from the posted Samsung sources, and last I heard on IRC before leaving my house was that some devs were having issues getting kernels to boot.
Now, the chip on our phones that handles USB has a UART mode, where the data pins on the USB connector get routed to a serial port instead of to USB.
I have a bunch of MicroUSB breakout adapters on order from Sparkfun now (http://www.sparkfun.com/products/10031) and will be picking up a few 150k precision resistors (150k is the value for UART mode) on Saturday most likely.
My questions:
1) Will this be useful to the other kernel devs for debugging?
2) Do our kernels even output anything to the serial port that the FSA9280 routes to, or is this bootloader-only?
Obviously the specific answer for our device is unknown since I don't think anyone has tried it, but has putting a 150k resistor on ID resulted in being able to get the kernel console on the serial port on GalaxyS devices? If it works on them it should work on ours.
No clue unless you try. ;-) Would make things easier if the kernel did get compiled with serial console though I would imagine.

I'll start working this once the parts arrive - will see how the Froyo kernels behave then we can try to migrate it to GB if anyone is still having issues then.
Of course it could all become OBE.

Ithink it would be pretty cool if you could break out to a proprietary apple connector. house it so you can adapt to any music dock that normally uses an ipod or iphone. That way we have integrated power and music out.
adam outler used the uart in a project and was hoping to find a way to unbrick without a jtag even with bad bootloaders. i have an arduino board like the one he used and could build his jig, i dont know much about kernels or c programming but if i can help figure anything out or if adams work (i havent kept up) was successful and we want an unbrick service for botched bootloaders and param.ifs let me know.
I need to get a USB to Ethernet adapter working with my HTC One S (T Mobile) and I am really struggling to figure out how to make this work.
I have the Apple USB-Ethernet Adapter, model number MB442.
That does not work inherently with the phone. It does work on my Asus Transformer, but not with the phone. I believe that the chipset in this adapter is the USB AX8817X.
So my question is, do any USB to Ethernet adapters work with the phones out of the box? And if so, which ones?
I'm relatively new to Linux/Android development so I don't know how to figure out if this chipset will work or how to compile and install drivers for it.
Any help would be greatly appreciated. Thanks.
Hey, I've been playing around with the initial bootup processes on my one, and I'm wondering if there are any UART pins on the board itself, and if so, would it be possible to access them to get a serial console during initial bootstrapping of the phone?
The 2 sets of golden pins on either side of the CPU board seem somewhat suspicious, but I figured I would ask here before ripping my phone apart and trying to guess which pins to use. Thanks!
