Hi,
The problem has finally caught me again by the hooks. The following code
works for only physical COM ports installed
====
>ManagementClass mc = new ManagementClass("Win32_SerialPort");
>System.Management.ManagementObjectCollection moc = mc.GetInstances();
>foreach (ManagementObject port in moc)
>{
> MessageBox.Show("Port = " + port["deviceid"]);
>}
====
I need to get the COM port on the USB and PCI as well.(All logical ports)
Any one can provde any pointers as to which "Win32_********" Management
class to use?
Regards,
Vipul Patel

on a PC
All:
I tried Vipul's suggestion on my computer and it worked fine until I
installed a USB serial port device. The original poster's solution of
looking in the registry showed the new device just fine on COM4 which also
showed up in the control panel by navigating to:
System - Hardware - Device Manager - Ports (COM & LPT).
However, the new COM4 did not show up using the ManagementClass method.
I presume that there must be yet another way to find all logical COM
devices installed.
