StarTech.com SV11151PEXT Stty -crtscts /dev/serial port, About Security Certificate Warnings

Instruction Manual

Under normal operations, this light should remain green. The R-Port connector on the rear panel also has an LED that mirrors the status of the light on the front panel. (Note: The rear LED status was reversed on some early units, where red=normal and green=fault. This does not affect operation in any way, but a green LED on the front panel and a red LED on the rear panel indicates that you have one of these units.)

•Hardware handshaking (CTS/RTS) is required for speeds exceeding 9600 bps. It is enabled by default on the SV1115IPEXT, but may need to be enabled on the other end of the connection. For Unix systems, the command is:

stty –crtscts < /dev/[serial port]

•A maximum of four users may simultaneously login to the same module. All users may type commands at any time, and all users will see the same output. Note the following:

•All users have equal access to all channels.

•A maximum of 16 R-Port modules may be connected at any one time.

•You plug-in and unplug any R-Port module at any time. When reconnected, it will automatically become available after a 15 second initialization period. Any log entries will be retained by the R-Port module while deactivated, but will not be available to users until it is re-initialized.

About Security Certificate Warnings

What is a security certificate?

Sites that employ secure TCP/IP (Internet) connections include a certificate that confirms that users are connecting to a legitimate site and are not being redirected without their knowledge. Certificates are issued by trusted third parties called Certificate Authorities (CAs) and contain essential details about a site that must match the information supplied to your Web browser.

Why do I receive a warning when I access the login screen on the SV1115IPEXT? As it redirects you to a secure (SSL) session by default, the login screen may generate a warning from your Web browser or the VNC Java client for two different reasons. First, the CA that has issued the certificate on StarTech.com’s behalf may not yet be recognized as a trusted source by the computer you are using to access the SV1115IPEXT. Second, since the unit could be configured in a number different ways, it is impossible to supply a generic certificate that will match your exact network settings.

Is my data safe?

Yes. The security certificate does not affect encryption effectiveness in any way, nor does it make the SV1115IPEXT any more vulnerable to outside attacks.

Can I prevent the warning from occurring?

Yes. You have two options that may prevent the warning from occurring. First, if the Web browser you are using offers the option to ignore the warning for future visits, the browser
