SCO OpenServer
Overview
Use this section to install and configure the RocketPort/RocketModem
SCO OpenServer Driver. This driver supports both the RocketPort
series of multiport serial boards and the RocketModem series of
integrated multimodem boards.
You can install up to four RocketPort/RocketModem boards in one
computer, including a combination of RocketPort and RocketModem
and ISA- and PCI-bus adapters. This driver supports a maximum of
128 serial I/O ports or modems per computer, and each port can be
driven at baud rates up to 230.4K bps, depending on the model of
RocketPort or RocketModem installed.
• All RocketModem boards support their own built-in modems
exclusively.
• All RocketPort boards support external RS-232 devices at speeds up
to 230.4K bps. Selected models also support RS-422 or RS-485.
For more information regarding the specific capabilities of your
RocketPort or RocketModem board, see the Hardware Reference Card
that is packaged with each board.
Note: While the driver and boards are capable of this performance,
older versions of UUCP and CU (prior to 5.0.4c) are limited to a
maximum baud rate of 38.4 Kbps.
This product was developed and tested using SCO OpenServer 5.0.4c.
You must install your RocketPort/RocketModem controller board(s)
before installing the device driver software. This section discusses how
to install, configure, and test the SCO OpenServer device driver
software.
If you need more information about baud rate support, see the manual
page for termio on your system. If you need to access rates higher than
38.4 Kbps, see the section on Baud Rate Mapping on page 18.
For more information about signals, cables, and pinouts, see the
Hardware Reference Card that came with your board and interface.
