InputLen

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

Available at design time and runtime.

MSComm32 and Comm64 have the same behavior.

         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:

This property affects the way that the Input property functions. When your application collects/retrieves data from the receive buffer (See the Input property) it will return a maximum of this many bytes. If more bytes exist in the receive buffer then you would need to call the Input property a number of times to retrieve all bytes from the receive buffer.

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