    Some communication software packages refer to RS-485 as RTS enable or RTS block mode transfer. One of the unique features of the ULTRA COMM+2.LPCI is the ability to be RS-485 compatible without the need for special software or drivers. This ability is especially useful in Windows, Windows NT, and OS/2 environments where the lower level I/O control is abstracted from the application program.
