FOOT SWITCH

Even though many applications do not monitor the status of the foot switch and do not have the ability to

perform specific functions base on closing or releasing the foot switch, we have decided to implement this

feature to the Router. Hopefully sometime soon applications will be able to detect the foot switch status and

use this this information for automating user functions like in the DOS based TRLog.

Router allows assigning a virtual serial port to the foot switch channel and selecting one of four available

input control lines (CTS, DCD, DSR or RING).

NOTE: CTS is not available if the foot switch channel is shared with the radio control port. The state of the

signal on the virtual port can be inverted by checking inverted box.

When a COM port is assigned for the foot switch but the application does not support foot switch status (or

no application is running), Router reports the channel as closed.

When an application opens the COM port (usually

at start-up), Router reports channel as open.

When the foot switch is pressed, this state is indicated by a red arrow.

SQUELCH PORT

Even though most applications do not monitor the squelch and do not have the ability to perform specific

functions based on its status, we have decided to include this feature in Router. Perhaps someday

applications will be able to detect the squelch and use this information for automated functions like audio

recording.

Router allows assigning a virtual serial port to squelch as CTS, DSR, DCD or RING.

When a COM port is assigned to the squelch channel in Router but not in the application (or no application

is running), Router shows the channel as closed.

When an application opens the COM port (usually at start-up), Router shows channel as open.

When squelch is closed, this state is indicated by a red arrow.
