Question: I'm using IDL to write to a serial port on a VAX/VMS system. I do this by pretending the port is a file, and write and read data to this 'file'. Is there any way to tell if the serial port has data to read back in, if I try to read from the port, and nothing is there, the computer will hang and then give an error. -- ------------------------------------------------------------ -------- Kevin Tritz | "Nuke 'em from orbit..."
