F5
 
Toggles local echo.  If you are transmitting characters through one modem 
to another WIT910, this allows you to see what you are typing. 
F6
 
Toggles stream mode.  Causes WinCOM to transmit a repeating pattern of 
characters.  Useful for testing.
 
F8
 
Toggles binary mode.  Displays extended ASCII and control characters.  
Useful for testing. 
PgUp
  Sets data rate of PC serial port to next higher value.  Value is displayed in 
status line.  Useful when WinCOM is used to change the WIT910 
interface data rate.  WinCOM can communicate at new data rate without 
having to exit and re-enter WinCOM. 
PgDn
  Sets data rate of PC serial port to next lower value.  Value is displayed in 
status line. 
 
The values of DTR (Sleep), RTS, DSR, CTS, DCD and the PC serial port rate are

6.1.1 WinCOM Tools 
There are four useful selections under the Tools menu. The first, Obey CTS/RTS is useful 
when just a three wire connection is made between the radio and the computer. Some PCs 
let the CTS input line float. If CTS is not asserted, the PC COM port will not send data. 
Unchecking this selection will have the PC COM port ignore the state of CTS and 
transmit data. 
 
When WinCOM’s transmit mode is used, data is sent continuously until the user stops it 
by clicking on Stop or pressing F6. If Single Transmit is checked, clicking the Transmit 
button will send the Transmit String a single time. There is no need to click Stop. 
Clicking on the Transmit button a second time will have the string transmitted a second 
time. 
 
The Packet Builder is an easy way to test the multipoint addressing mode of the WIT910 
radio. Since the WIT910 operates in a star configuration in multipoint mode, only the 
base radio needs to address data to specific remotes. All remotes send data back to the 
base and do not need to address the data to the base. To send a packet of data to a specific 
remote in a multipoint network, enter the handle of the desired remote in the Handle 
window. Type whatever data to be transmitted in the Data to Transmit window. In the 
bottom window, you will see the entire packet being built as the data is entered in the 
windows. When all the data has been entered, click on the Transmit button to send the 
data.
