Once you've installed Talker on your Macintosh, you can listen to other users on your network. Talk•In is used to monitor the network for traffic from anyone who wishes to talk to you. This chapter describes how Talk•In works and how to use the Talk•Control control panel to adjust the Talk•In application.
*Talk•In works by receiving the digitized sound packets generated by Talk•Out on the network and playing it through your speaker. Before you can listen to other users you need to be connected to an AppleTalk network and any user who wishes to talk to you must have their computer on and the Talk•Out application running and connected to you. The Talk•In application always runs in the background. It is automatically started when you start your machine. Talk•In allows other users to see your name in their Talk•In window and to monitor the network for communication from the Talk•Out application.
CONTROLING TALK•IN WITH TALK•CONTROL
Pull down the Apple menu on the left side of the menu bar and choose Control Panels. Double Click on the Talk•Control control panel to open it.
HANDLING INCOMING MESSAGES
You may handle incoming messages in three ways:
1) Normal Mode: Talk•In will play the sounds coming from a user with Talk•Out without any notification or restriction.
2) Privacy Mode: No sound will be transmitted to you while privacy mode is on. Talk•In will alert you that another user trying to contact you by flashing a notification icon over the Apple Icon. You can then receive calls by switching to the Normal mode.
3) Off Mode: Talk•In will not be operational. Your Network Identification will not appear in any other user's Talk•Out user window. Off mode is established by pressing the QUIT button.
Volume Control:
The speaker volume can be adjusted using this control. There are eight settings which correspond to the settings in the Sound Control Panel.
Delay Buffering:
The delay buffer is used when operating over a slow network link such as AppleTalk Remote Access with lower speed modems and or server. The delay may be as much as several seconds depending on the conditions. System memory may be used when there is plentiful memory available at all times. If you often are low on system memory (many large applications running simultaneoulsly), you should allocate an additional 512KB of memory to your Talk•In application using the Get Info section on your file menu and use application memory.
System Memory Radio Button:
Click this button to use system memory for the delay buffer.
Application Memory Radio Button:
Click this button to use the application memory for the delay buffer.
Memory Usage Gage:
This indicates how much of the buffer is in use during delay operations. It will fluctuate depending on the network traffic and network capacity.
Quit Button:
Press the Quit button to stop Talk•In operation and remove Talk•In from memory. When this has been done Talk•In is no longer operational and will not handle incoming calls. In addition your name will not appear in any other users Talk•Out user list so they will not be able to contact you.
Launch Button:
Press the Launch button to start Talk•In operation. Talk•In will begin monitoring the network for incoming calls. Your name will appear on the other users Talk•Out user list the next time it is refreshed.
