Serial port on VB.net using old mscomm

[gccosta]

i'm trying to use the msComm ActiveX on vb.net and when i to this code:

serial = New AxMSCommLib.AxMSComm
 
        serial.CommPort = CommPortt
        serial.Settings = CommBaudRatee & ",N,8,1"

i get an error:
serial.CommPort <error: an exception of type: {System.Windows.Forms.AxHost.InvalidActiveXStateException} occurred>

what should i do to use this ocx on .net??

Thank you,
