New Serial Port Added

**pestocat** · 06-Apr-2011, 12:31

I used the Yast utility to add me to the uucp group. Now I don't get error message from the application that it can't open the serial port. But I can't get any data from my device (it works in Windows version). Do you suppose I need to configure the serial port card. I have set the parameters in the application.

Yes, you may need to configure with setserial. This will tell you how ttyS0 is currently configured

Code:

setserial -g /dev/ttyS0

Refer man setserial for config options.

Another good way to test the data coming from your serial device, may be to use minicom to capture it first. When you are happy with this, then see if the wine app is ok with it.

deano, you are so patient. Everything checks out. The port address is correct and irq is correct. But I still can't pass data. Do you suppose I need to add something else to a group like maybe wine or winsdr.
Thank you

1) Lets have a look at

Code:

ls -l ~/.wine/dosdevices

2) Did you try minicom connectivity to check the serial port config/data from the device (assuming its possible for this device)?

The ls -l ~/.wine/dosdevices looks OK I see /dev/ttyS0 so that should be OK. I checked for baud rate and it is set to 57600 as I set the application item. I can't get minicom, I tried to load it and I can't find my CD. I'm usually good at keeping my disks in order, but....

Maybe its a handshaking or parity issue? What kind of device is it as a matter of interest?

If you have internet connectivity, install the minicom package via zypper:

I'm sure the added serial card needed a driver installed. The first card had a CD but Linux couldn't read it. I tried another card, Linux could read the CD, but there was no driver available. Next I purchased a USB to serial converter and this works fine. Now I'm able to read data stream with no problem. Thank you for all the assistance, it is much appreciated.

Glad you've got it sorted. I use a usb to serial device (uses the pl2303 driver) for my work configuring swtiches and routers occasionally. It works very well. (I wondered and mentioned about whether a proprietary driver may have been required, but as you had /dev/ttyS0 present I didn't pursue it further). Anyway, at least you have gained some good serial interface troubleshooting skills now.
