C3000 Usb Serial

Well that is good news.

But, er, um, I`m not sure what cable you are talking about.  Can you give a URL for it? 

I was, and still am, under the impression that the only way to get serial IO on the C3000 is either via the USB host or via a dedicated CF card. 

I was sure the "hidden" port connector of the C3000 doesn`t do serial, but I`d love to be corrected.

No problem, just click [a href=\"http://www.amazon.com/exec/obidos/tg/detail/-/B0000645V7/102-2950216-6288937?v=glance]here[/url] for a link to the cable (on Amazon). It's the CE-170TS, the serial cable for the 5500 & 6000 (and also the C700,750, etc.). I successfully connected to a Cisco router and a SBC (Single Board Computer) and was able to enter commands, etc.

Now here's the strange thing. There are three, count them, three serial ports that show up in dmesg. The first one is the one for the serial cable above & the second says it's IrDA. But what about the third?

Aha! So it _is_ connected to the hidden sharp IO port then?

Does that mean you removed the "don`t remove me" cover to the hidden IO port and just plugged it in?  Just want to be sure before I do something to my Z that I really shouldn`t do...

Not sure about the ports showing up in dmesg, but I do recall other kernel modules doing similar things.  Maybe the controller chip is dual port but there is only one port connector.  That way the two ports show up in dmesg but only one is physically accessible.

Thanks,

Jonathan.

I want to use SL-C3000  to send command  to RS-232 port of a controller device.
I need confirmation that this port can do RS-232 communication.

Yep, all I did was remove the cover and plug in the cable. I remember reading on the web that the USB cable wouldn't work (no surprise there -- I'm sure the pins got routed to the mini-AB port), but that they hadn't checked the serial cable.

Great!  Thanks for clearing that up.  I read exactly the same thing and assumed the serial was also crippled.  

Now how do you take off the little plug/cover without breaking it or scratching the pretty finish of the C3000?

I wonder if removing the plug voids the warranty?

I`d prefer using the built-in serial to using a USB serial port adaptor which has crippled drivers.

Cheers,

Jonathan

The cover comes off with a fingernail and reattaches just as easily. IMHO, it's not really designed to keep you from using the port, it's just there to make the case look cleaner.

By the way, do you have a working serial terminal program for the C3000? My copy of minicom can't draw any ascii boxes (for the dialogs) and leaves the screen looking a mess. If you have a better version, could you please let me know where you got it?

Thanks,

Jason,

have you used tipterm?  It is like Solaris tip command.

Nope I haven't used tipterm, but I've heard good things about it. Thanks for uploading!

Jonathan,

does your driver work with ALL usb-to-serial cable ?

...
Rename this file (pl2303_DT.o) to pl2303.o and use in place of the one in my archive.  Maybe it will work...

Best of luck.

Nope, the pl2303 drivers work for pl2303 (and pl2303x) devices only.  

But I did compile all the other serial drivers in the kernel source at the same time and they should be included in this file:

usb-serial (zip)
or
usb-serial (tgz)

Give them a try.  Instructions included in these archives.

(Note that pl2303_DT.o is a special driver for a pl2303 device with aaa0 id.  It was compiled for DreamTheater and you're unlikely to need it.)

I have to ask, why any did not use BT-serial?  A drawback with BT-serial is that you need to power it, but you can build a USB power cable for your adapter and power it from your Z.

good question. in fact, i've used the Aircable zaurus bluetooth adapter

it works perfectly with the SL-C3K, i want to power the serial side of it with a battery pack though, because most routers don't have a ps/2 or usb port to get power from

i use it to dial-in with GPRS using my nokia 6310i, the bluetooth connectivity is a bit flakey (i developed a healthy hate towards nokia for this), but once the 2 bluetooth devices sync and connect I can sent AT commands and set up a PPP connection over GPRS
