This is a direct quote from the microsoft help pages for the MSComm Control:<br />
<br />
&quot;You can set value to any number between 1 and 16 at design time (the default is 1). However, the MSComm control generates error 68 (Device unavailable) if the port does not exist when you attempt to open it with the PortOpen property.&quot;<br />
<br />
You can only set up to 16 with this control. &nbsp;You will have to use API's to open above 16.<br />
<br />
There is a sample of using the API at:<br />

Hi,<br />
I can see in the help file that at DESIGN time it is only possible to open comPort 1 to 16! <br />
Well I Want to open Comport 17. I guess I have to set it in RUNTIME then.<br />
If I try to to this :<br />
Mscomm.CommPort = 17, then I get this error :<br />
8002 Invalid Port Number!!<br />
<br />
Is it not possible by the Mscomm to open a port that is greater than 16???<br />
How should I do it then? I can see that my hyperterminal can open COM17, What special do they do?<br />
Pleaz help me!

Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.
