Post Installing OS using TS serial port
So I'm following the guide here for installing Debian on the trimslice. I've got the SD card all prepared (that went AOK) and I finally found a serial to USB cable.

However when I get to the "Boot SD" section, things are falling apart on me. Running:

Code:
screen /dev/ttyS1 115200,cs8,-ixon,-ixoff


From my main system yields a result of:

"/dev/ttyS1" is not a screen. Sorry could not find a pty.

Any idea what is wrong? I've got the serial cable connected from the USB on my PC to the serial port on the TrimSlice and the power light on the trimslice is coming up...

Never used screen for tty access, you could try /dev/ttyS0, /dev/ttyS2, first.
Or install another program like putty.

Tried the first dozen or so ttySX with the same result.

Isn't putty a Windows only piece of software? How else can I get into my Trimslice from a Linux box?...

If you are using a USB serial adaptor the device will probably be /dev/ttyUSB0 or similar.

Getting closer!

/dev/ttyUSB0

Is getting me no error messages, but simply giving me a blank terminal. Any ideas on if anything else might be wrong in that guide for installing debian?

Sorry I've never used screen to try and access the trimslice - I normally use minicom (from a Fedora 15 host)

The command line that works for me is

minicom -D /dev/ttyUSB0 -b 115200

Hrm, minicom is simply showing me:

Code:
Welcome to minicom 2.4

OPTIONS: I18n
Compiled on Jan 25 2010, 06:49:09.
Port /dev/ttyUSB0

Press CTRL-A Z for help on special keys 


Ideas?

Just to check a couple of things

1) You have started minicom before powering up the trimslice
2) You only have one USB to serial adaptor (something like ls /dev/ttyUSB* would list any others)
3) What cable are you using to connect the trimslice to your USB/serial adaptor?

Correct, just one.

I have a fairly generic USB to 9pin serial adapter with a female-to-female gender change between this cable and the serial cord that came with the dev kit.

Thanks for your help trying to get this rolling by the way.

As far as I am aware most serial adaptors have a 9pin male (so no gender changer should be needed) - I wonder if the one you have has a different pin assignment so it can be connected directly to a male serial adaptor without the need for a crossover (null modem) cable. Do you have a model number for it?

Do you have a null modem cable and another female-female gender changer which should then reverse the swap (if my assumptions are correct)? Or could you make up a suitable cable (I could probably help with the pinouts if you need).
