Use an USB-serial port converter

I have compiled sources for USB-serial converters - enjoy the attached file. :)
Quickly tested with ATEN UC-232A (pl2303.o module):

insmod usbserial.o
insmod pl2303.o
mknod /dev/ttyUSB0 c 188 0
chmod 666 /dev/ttyUSB0

Hi Technik,

I have used your compiled modules with a PL2302 based usb-to-serial adapter. The modules are loaded without any errors and also the adapter was recognized correctly when plugged in (check by using dmesg). But when I am
sending only a few characters to a connected modem the system stops and reboots due to the running watchdog.
How you have checked the modules?
Which firmware are you using?

Yes I have tested it quickly with (a bit obsolete) 1.7.5.9-1 firmware. I did not encounter any router reboot and it seemed to be working (Hyperterminal versus microcom terminal, 9600-8-n-1).
What is your free memory size?

BTW the 2302 chip is quite different so perhaps it can't work with pl2303.o module at all. It looks strange to me that your chip was accepted by the driver...

Hello,

does anybody get such a converter to work with wl500g ?
I dont want to open the case.
Does anybody have experience with profilic driver ?
Maybe i missed some discussion in forum ?

Thanks a lot.

Regards,

Gabriel

See http://www.usbgear.com/
It's on the mainpage!

NOTE: Google string: USB Serial!!!!

But i cannot find any information there wether this would work on the asus wl-500x. Besides, what do you want to use serial connections to the wl-500x for? Just enabling serial connections does not help much.

wl500g <-> USB - Serial RS232 <-> RS232 microcontroller with several status functions...

A server program watches the microcontroller and sends udp broadcasts
to internal net or wait for a TCP terminal connection (small daemon process).

Hi

For general, it can work if the needet modules are compiled into the kernel what i cant tell you at the moment. I have a Belkin usb-rs232 device which is suported by linux at my pc, and also the usual cables with inbuild electronics (mostly the ftdi chip) are supported.

What Mikrocontroller do you use ? AVR,Pic, Basic Stamp ??

I want to use AVR, 90S2313 for simple solution, Mega series for more ports...

Hi

Just for interrest, the Belkin Serial Adapters work also.
But what to do next with them :).

Code:

---

hub.c: new USB device 00:04.0-1, assigned address 2
usb.c: USB device 2 (vend/prod 0x50d/0x103) is not claimed by any active driver.
usb.c: registered new driver serial
usbserial.c: USB Serial support registered for Generic
usbserial.c: USB Serial Driver core v1.4
usbserial.c: USB Serial support registered for Belkin / Peracom / GoHubs USB Serial Adapter
usbserial.c: Belkin / Peracom / GoHubs USB Serial Adapter converter detected
belkin_sa.c: bcdDevice: 0205, bfc: 1
usbserial.c: Belkin / Peracom / GoHubs USB Serial Adapter converter now attached to ttyUSB0 (or usb/tts/0 for devfs)
belkin_sa.c: USB Belkin Serial converter driver v1.2

Hi,

I also want to use an serial usb adaptor, other make (type DCU-S2U), works fine in other Linux or Windows machine, is recognised perfectly on boot-up,
but after a few characters, same problem, locks-up and then leads to a reboot of the Asus.

I have tried:
- Changing the settings of the port with ssty (disable software and/of hardware handshake)
- Using proper hardware handshake connections
- Several firmwares for the ASUS
- Adding proper end-of-line and end-of-file characters to the data

Nothing works, looks like a bug in the firmware :mad:

Anybody who has a clue??? I would be VERY gratefull if this problem could be solved.

Regards,

Peter

Hi,

If it insert the usb to serial convert cable to WL-500g then there will be many useful apllication. Remote other device control and communictaion with RS232C... Unfortunatly, I don't know Linux system programming.
I have only its idea. :(

Starting with 1.9.2.7-5 support for pl2303 and generic usb serial adapters was added to the firmware.

I have connected an usb to serial converter, ATEN UC-232A (pl2303.o module) to my asus 500g.
Which port number should I use if I want to connect to the converter over a wireless tcp connection? I suppose
that the IP is the same as the IP of the router?
