Input Retrieves (reads) data from the receive buffer. ReadOnly MSComm32 and SComm64 have the same syntax and functionality. Syntax:- value = SComm1.Input   value:- A String or an Array of Bytes depending on the current state of the InputMode Property     Example reading a character string. SComm1.InputMode = 0 Text1.AppendText(SComm1.Input)   Example reading an Array of Bytes. SComm1.InputMode = 1 dim b() as byte b = SComm1.Input Remarks: Both MSComm32 and our SComm64 component use the .InputMode property to indicate whether data is to be received as an array of bytes or as a string. In VB6 the return value of the .Input method was a variant that could then be interpreted as either a byte array or a string. But Microsoft's MSComm32, when used in .Net, returns an object. In Visual Basic this functions the same as a Variant. But in C# it needs to be cast to (string) or a (byte[]) c# example: SComm1.InputMode = SCommLib .InputModeConstants .comInputModeBinary; string s = (string)SComm1.Input; // (string) is the cast from object to string. Our SComm64 component has the same syntax as MSComm32 so, in VB or C# no code changes are necessary. (Note that in C# you need to use the InputModeConstants (same as C# with MSComm32))
