Fedora Franklin CDU680 problem. WvModem: Cannot get information for serial port. # setserial /dev/ttyUSB0 Cannot get serial info: Invalid.

Ok, so I know what you are trying to achieve. I was thinking that you have problems with connection to serial console. Anyway as you see in this separate thread this functionality is not supported yet and to be honest I don't know current status of this functionality. But anyway in output from your dmesg you can see: Xen virtual console successfully installed as ttyS0 Please try to use different port. >I have try to connect the UPS with server via USB, the communication is OK >but if connect via serial port, the communication is not available The problem is that hypervisor use serial port to communicate current status and some debug output. So I am not entirely sure if it is possible to share this serial device to other purposes.

Cannot get serial info invalid argument ttyusb0

Please show me content of /proc/cmdline root=LABEL=root-gjaybust ro quiet vga=785 splash 2. Output from command: dmesg grep -i 'serial console tty' [root@localhost ~]# dmesg grep -i 'serial console tty' Xen virtual console successfully installed as ttyS0 Console: switching to colour frame buffer device 80x30 Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing disabled 8250_pnp: Unknown symbol serial8250_unregister_port 8250_pnp: Unknown symbol serial8250_register_port 3.Can you please let me know what you are trying to achieve? The purpose: install our software on the xs host, the software is used to monitor the UPS(The device supplied the power to server), when the power fail, our software will send the 'poweroff' command to the host to shutdown the host and VM gracefully I have try to connect the UPS with server via USB, the communication is OK but if connect via serial port, the communication is not available I found the similar issue occured,please refer to the web page. Radoslaw, thanks so much 'The hypervisor use ttyS0 to communicate current status and some debug output'---that's to say, the ttyS0 is in use all the time, so our software cannot open the serial port ttyS0 because it is busy. I have tested with the USB-Serial Adapter instead of the serial port attached to mainboard, it works. Connect the UPS with server via USB-Serial Adapter, 'ttyUSB0' will appear under the path of '/dev' the communication can be established via '/dev/ttyUSB0' Edited by: liu qiong on 2010-8-31 上午1:51.

We will begin by verifying that your cable, the PC COM port, and the oscilloscope COM port are working correctly. Is your cable a Null-Modem style RS-232 cable?

If you are not sure, read the section RS-232 Cable Issues. If yes then go to next step. Have the communications parameters been set properly on your oscilloscope?

If you’re not sure see the sectionCommunications Parameters. Dilwale dulhania le jayenge full movies mp4 download. You may also need to refer to the operator/users manual for your oscilloscope to determine how to set these parameters.

If the parameters are set correctly go to next step. Are the COM ports on the oscilloscope and PC functioning properly?
