Hi everybody

I'm trying to get a list of all the serial ports that are on a machine ie
COM1, COM2 etc. I found an API function called GetSerialPortsList, this
returns a char pointer with all available comm ports in it, However I get
Unresolved external symbol error. Does anyone know how to get this running
or do they know another method for finding the available commports on a
system?

Thanks in advance

Andrew

I don't know such Win API function.
Windows uses Configuration Manager's functions for enumeration 
devices. Configuration Manager is a part of DDK but 
available for using without building DDK environment.
You can use C++ Builder for enumeration.

TPortControl component can do enumeration in design and real 
time (source code and help file included):

Now I am finishing article about enumeration and managing FIFO 
control(and put it on codeproject site about some days). 

Vladimir.
