FUNCTIONAL TEST

The following test sequence will verify that your pole display is working
properly. Before you start this procedure, you must install the pole display
correctly as outlined under the INSTALLATION section. The functional test
should be done under MSDOS command prompt by booting up the
computer in DOS mode, or shell out to DOS prompt (in Window95/98/ME) or
COMMAND prompt (in Windows NT/2000).
NOTE: T he actual key entries in the text below are enclosed within
quotation marks ( “ ” ). Do not type the quotation marks as part of

This test procedure assumes the pole display is connected to COM1 of the
computer. If COM2 is being used, type COM2 where COM1 is called out.
Close all opened application programs that use the same COM port before
shelling out to DOS COMMAND prompt. Enter the following command lines
to open the COM port for communication with the pole display:
Type “MODE COM1 96,N,8,1” and press the ENTER key.
Type “TYPE CON>COM1” and press the ENTER key.
