Re: help in connecting with COM port
The error message is pretty straight forward. Some other program currently has the port open.
A comm port can only be accessed by one program at a time.

Re: help in connecting with COM port
If the dialup is connected at the time then perhaps the manager is using dialup services.
The bottom line is that you can not open a port that is already open.
Also can't help but notice that so far this does not appear to have any thing to do with VB.
