Unsafe characters

URLs use some characters for “special use” in defining their syntax and should be encoded. For various reasons, these characters present the possibility of being misunderstood within a URL, and are therefore considered “unsafe”.

The table below lists unsafe characters.

Advanced Serial Port Control

If serial setup configurations are required, the following options provide advanced methods for communicating serially with the interface: serial pass-through (or redirect mode), direct port access, and serial bridging.

Serial pass-through (redirect mode)

Serial pass-through allows serial commands from a controller to “pass through” an IPL T S interface on route to an A/V device, as shown in the following figure.

Any serial port on an IPL T S interface can be configured as a pass-through connection to another serial port on the same device.
