VPX-128 Multiplexer connects up to eight devices (seven serial and oneparallel) to a single workstation serial port and up to 16 devices to theworkstation system. Unlike Ethernet terminal servers, VPX-128 connects tothe RS-232C port and does not use network bandwidth. VPX-128 comes withinterface software that eliminates future ROM changes. The softwareoffers automatic device configuration and allows for default changes indevice assignments. The device features include:

Dial-in/dial-out modem access with UUCP-compatible record locking.
Enable flow control using XON/XOFF, CTS, and RTS for attached devices.
