Additional Com Ports with MSCOMM control

[Motor11]

Hello all,

Is there a way to access additional comm ports (say, up to com24) with the MSCOMM control? Is the API the way to go?

Regards,

never needed to go as high as 24 but MSDN states

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.

whether that means the port is limited to 16, or whether it is just limited to 16 at design time i dont know.

good luck

Thanks ADoozer,

Unfortunately it seems that the control is also limited to a max port of 16 -whether at design time or in code. I was just fishing for a work around. There are commercial Comm port controls that overcome this limitation, but the one that I've used was so buggy that I decided to go back to MSComm.
