InputLen

Sets or Retrieves the number of bytes to be read from the receive buffer.

Available at design time and runtime.

MSComm32 and SComm32 have Similar but not identical behavior. See Remarks below

Syntax object.InputLen = value         object Name of the communications control.   value A numerical expression indicating the maximum number of bytes to be retrieved by the Input property.         Examples object.InputLen = 1 '// Set the value (receive 1 byte at a time)             Text1.text = object.InputLen '// retrieve the current setting

Remarks:

The default InputLen is 0 (zero). The Input property will retrieve ALL bytes from the receive buffer.You would usually only wish to change this property if you needed to read data in fixed/known length packets.

If .InputLen is set to a value above zero then .Input will return a maximum of this many bytes. If more bytes exist in the receive buffer then you would need to .Input a number of times to retrieve all bytes from the receive buffer.

SComm32 has an improvement over MSComm32.

If this property is > 0 but less bytes exist in the input buffer then SComm32 will "Look Ahead" and if possible return with the requested number of bytes.
