Use an USB-serial port converter

[Technik]

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...

But what to do next with them .

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

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

Regards,

Peter

I also have some problems with the usb-serial-FTDI module...
It works, but I don't get "newline"... and if I echo a lot of chars, it stops after the first 100 or so...

If you know the solution, please post it here.

thanks.

UPDATE:I just solved this problem...
I recompiled usbserial.o and ftdi_sio.o (from oleg's custom fw),
and now it's working...

PS: [Technik] : Empty your mailbox!!! you want to send you a PM!!

Can you post your newly compiled drivers (usbserial.o and ftdi_sio.o)? I have a ftdi module that won't work, maybe the new drivers also solve my problems.

Here it is... (tested with Oleg's 1.9.2.7-6b)
use:
insmod ./usbserial.o
insmod ./ftdi_sio.o

Works great for me to! However I have another question. Can I connect to the serial port on the router from a computer connected to the network?

I'm not sure if I should post on this thread or create a new thread. My goal is to use a Belkin USB to Serial adapter with my WL-500g (not the Deluxe model) to create a PPP connection for my DirecTiVo. I admit that I'm a novice when it comes to Linux. I know how to create the connection on a Windows based system, though I haven't found instructions yet on how to do it via Linux. My main question for this forum is: Has anyone tried using the USB to Serial adapter to create a PPP connection via the WL-500g?

Thanks

@GWL - these modules are what I am looking for let's see if I can get things running on oleg "1.9.2.7-7g". I assume it is for kernel "2.4.20"?. -- it looks good dmesg:
