Launching SI_SCOPE

Before running SI_SCOPE it is a good idea to save the settings you have entered. To save the current settings open the file menu and click on the "Save" option. The next time you run SCOPECFG your settings will be restored.

To start analyzing a serial line make sure you have the SI_SCOPE cabling properly connected to the two ports you are using. For directions on hooking up the cabling see Appendix A. Once the cabling is connected and all the port information described earlier in this section is properly entered you can start SI_SCOPE by clicking on the "Run" menu option. When SI_SCOPE has finished loading you will notice that the word "WIN" is displayed in the upper right hand corner of the screen.

You can also launch SI_SCOPE from a command line without running SCOPECFG. To do this run the program si_scope32.exe that is in the directory where you installed SI_SCOPE. When running from a command line you need to pass the port and irq information on the command line. The command line options are:

OPTION	MEANING
/B:##	Specify communications buffer size in kilobytes
/I1:##	Specify IRQ used for port1
I2:##	Specify IRQ used for port2
/P1:####	Specify the decimal address of port1
/P2:####	Specify the decimal address of port2
/NO16550	Turn off 16550 UART detection
/NOALERT	Do not alert user on line errors
/ARCHIVE	Archive capture files
/NOSTAMPS	Turn off time stamps
/FLUSH:##	Flush the capture file to disk every ## seconds.
/AUTO_ARCH:hh:mm	Auto archive the capture file at the specified time each day. Time is specified in a 24 hour format and must be zero filled as follows: 05:45.

Note:

• All the parameters represented with a # sign are assumed to be in decimal not hexadecimal. If you want to pass a number in hexadecimal end it with the letter h. Therefore to set port1 to COM3 you could use /p1:1000 or /p1:3E8h.
• Increasing the size of the communications buffer with the /b: option will decrease the size of the Memory Window buffer. This option does not change the size of the buffer used by SI_SCOPE 's kernel driver. To increase the size of the device driver buffer see the section Configuring SIDRVR .
• In order to support users with custom systems SI_SCOPE will not check the validity of any of the command line parameters, therefore you can use any IRQ or any port address. (Be careful if you pass the wrong address SI_SCOPE will use it and crash!).
• Any parameters not specified will be set to the default values of: /b:1 /i1:4 /i2:3 /p1:3f8h /p2:2f8h
