2.5.3 Resetting Extended Baud R ate Selection on Power Up
The PCI-COM232 board will power up with the UART Clock Rate set to 1.8432 MHz. If you change the
UART Clock Rate via the Device Manager Property Page (in Windows 95 or 98) or via the PCIcom
applet (in NT), you must execute the ComSet32.exe application to restore the settings after a reboot. The
Device Manager configuration dialog writes the chosen settings to the registry. The ComSet32.exe
application reads the settings from the registry and restores the PCI-COM232 hardware configuration.
During installation, the user has the option to install a shortcut to ComSet32.exe in the Startup folder. If
you select this option (YES), your PCI-COM232 hardware configuration is maintained across reboots. If
you select NO, at each reboot the PCI-COM232 board is restored to its default configuration.
Note: For most applications, the default settings for the hardware are adequate and allow the board to
operate at up to 115.2 kbaud.
If you selected NO during installation, when prompted about installing ComSet32.exe, then you can
manually create a shortcut and copy it to your Startup menu. The ComSet32.exe application is installed in
the directory specified during installation. The default installation directory is C:\cb. To create a shortcut,
do the following:
Start the “Windows Explorer” application and open the installation directory.
Right click on the “ComSet32.exe” entry.
Select the “Create Shortcut” option from the drop down menu.
Copy the shortcut to the Startup folder (C:\Windows\Start Menu\Programs\Startup).
To keep the ComSet32.exe window from popping up during execution, set the shortcut to execute
minimized. To set this option, do the following:
Right click on the shortcut icon and select Properties.
Select the shortcut tab.
Set the option labeled Run to “Minimized”.
