be much appreciated if someone could help me out, thank you. Moors7 2014-11-07 12:23:07 UTC #2 I believe the problem lays in resetting the putty serial connection black screen Core when there's still a connection. I've noticed the same behavior with the arduino IDE. Could you try disconnecting putty beforehand, or restarting it after the Core, and see how that goes? OddieCAT 2014-11-07 12:28:16 UTC #3 putty is disconnected http://answers.microsoft.com/en-us/windows/forum/windows_vista-hardware/usb-to-serial-not-working-using-putty/03aaba4b-ddef-494d-93bc-c295e30ad653 inbetween using the core in listening mode and the core being reset, if that's what you mean. I have also had the similar problem when trying to use the IDE but when the core isn't in listening mode, the IDE seems to not acknowledge the core is connected. I assume this is the same problem. OddieCAT 2014-11-07 15:31:34 UTC #4 Solved, was an error in coding line while(!Serial.available()) SPARK_WLAN_Loop(); was before line Serial.begin(9600); peekay123 2014-11-07 15:51:03 UTC #5 @OddieCAT, though https://community.particle.io/t/solved-using-putty-as-a-serial-connection/7917 Cis still in the code, it really should be replaced with Spark.process(). UPDATE: It turns out that SPARK_WLAN_Loop() is the correct function to call. @BDub and @mdma are presently assessing whether Spark.process() should be used. jmosk 2016-04-13 20:42:50 UTC #6 I am having the same issue that started this post. Although the solution posted is not appropriate for what is going on. The Photon is COM3 on my Win 7 machine. I flash and test the Photon and use puTTY to obtain debug information. Then I update the firmware, re-flash the Photon, and start a new puTTY session. Since the Photon will disconnect and reconnect COM3 when it reboots after flashing, I close the puTTY session and start another. But I can't start another debug session because I get the same "Unable to open connection to COM3 Unable to open serial port".message. I have to reboot the Win 7 machine to start another debug session which certainly takes forever. Can't do many debug runs if you have to reboot the main computer each time. I attempted to disable and enable the COM3 port using the device manager on Windows. But it just hung trying to disable COM3. Although aborting the process and trying again did show COM3 as disabled. Enabling the port also hung and stopping and starting the manager once again, showed the device enabled again. But it still would not allow access to COM3.

Hello, I unable to open am trying to use Putty to connect to a Cisco router via a serial connection. This is to configure the router out of the box. Security is not a problem until it is connected to a network. Then it will be confgured with SSH. Serial line: /dev/ttyUSB0 Baud rate: 9600 Data bits 8 stop bits 1 Using a Cisco USB serial cable. When I try to connect I get this error. Putty Fatal Error Unable to open connection to: Unable to open serial port OK Checked and it looks like it is using the correct paths. /usr/bin/telnet :~$ echo $PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/loc ls -l /usr/bin/telnet lrwxrwxrwx 1 root root 24 Feb 13 22:14 /usr/bin/telnet -> /etc/alternatives/telnet/usr/bin/telne I have connected via minicom. My friend uses CentOS and is able to use Putty with my cable. Also tried CtkTerm. Received this message. Cannot open /dev/ttyUSB0: Permission denied Any help would be appreciated!!!

Greetings, I'm trying to connect to a Cisco 2900 Series Switch from a Windows 7 Pro box via serial to rj-45, using Putty and not able to connect. I found this video via youtube and did everything he did and I'm not able to connect. YouTube - Using Putty for Connecting to Cisco Devices I noticed that Windows defaults to com1 and I changed that to com3 like the example and it still isn't working. When using Google noticed a few threads saying that legacy hardware, like the serial port is going the way of the dinosaur...so with that being said was wondering if anyone has an issue like this and if they were able to work thru it or should I just get usb to rj-45 cable? thanks Quote Login/register to remove this advertisement. tiersten was here.

You have to use the com port number assigned by your OS i.e. COM1. Originally Posted by JockVSJock When using Google noticed a few threads saying that legacy hardware, like the serial port is going the way of the dinosaur... Legacy ports like RS232 serial are no longer part of the integrated motherboard hardware any more. Legacy RS232 hardware is still supported by Windows and every other major OS. If you want RS232 serial on a machine that doesn't come with it built in then you have to use a USB serial adapter or buy a RS232 serial expansion card to fit into your computer. USB serial adapters will generally require a driver but not all of them do.

What specific cable are you using to go from the serial port to the console port on the switch? You sure th
