Verifying Installation
If the hardware and software installations were successful, the
following message displays for each board after you reboot:
% Rocket ###h - ###h- - YYY nports=X vx.xx
Where ###h - ###h is the I/O address of the board, YYY indicates ISA
or PCI board, X is the number of ports on the controller, vx.xx is driver
revision number, and is the driver release date.
Note: The driver sees all RocketModem ISA boards as 8-port boards.
If the installation was not successful, the following message displays:
% Rocket xxxh - xxxh- - board X NOT FOUND vx.xx
Where X is the adapter number (1-4) that was expected to be in the
system but could not be detected by the driver, and vx.xx is the driver
revision number.
The nports statement may also display the wrong number of ports.
For help resolving installation problems, see the Troubleshooting on
page 32.
Configuring Ports
The RocketPort/RocketModem SCO OpenServer device driver
provides three device types:
• Non-modem (Direct) Control
Enabling direct device names allows communications without the
carrier detect signal being present. It also allows for 3-wire
connections with non-modem serial devices, using the TxD
(transmit data), RxD (receive data), and SG (signal ground).
• Modem Control
The modem device names require modem control to function
properly. Specifically, the carrier detect signal must be present
before the serial port becomes active.
• Transparent Print
This is an output-only device that allows you to access the auxiliary
port on a terminal.
Regardless of the number of ports physically present, the driver creates
32 devices in the /dev directory for each board installed. (This is to allow
for the maximum number of ports possible.) Device names are assigned
as shown in Table 3 on page 16.
