Purpose Use this guide for the following: • An introduction to RealPort, how to install, configure and use RealPort and, how to troubleshoot should you encounter a problem • Configuration examples • Administration procedures Audience This manual is intended for the person responsible for configuring and administering RealPort. This person should have experience configuring network devices and be familiar with networking concepts.
The number of ports for each Digi device. Include any Xem PORTS Module ports that are attached to the Digi device. • Determine the link speed between the host machine and the Digi device if a slow WAN link (for example, a 56K leased line) connects them. Configuring a PortServer or PortServer II for RealPort Use this procedure to configure a PortServer or PortServer II for use with Digi RealPort drivers.
RealPort, on page 2-2. 4. Install the RealPort driver. See the following procedure. Uninstalling RealPort Use this procedure to remove the Digi device driver software from the kernel by using the program /usr/sbin/realport_uninstall. Procedure 1. Log onto the console as super-user (root), and enter this command: realport_uninstall [system_name] The system_name is the name of the kernel where the RealPort driver is installed;...
When used with a terminal or other device, it is usually wise to use a modem TTY definition label and to wire the Digi DCD signal to the terminal's DTR (Data Terminal Ready) line. When the terminal is turned off, any associated jobs are killed, and the user is logged out.
Note: stty-ncxa is also called ditty for compatibility with other Digi International software. ditty is the same as stty-ncxa and can be substituted for stty-ncxa in commands described in this documentation.
Configuring a Device for a Printer Use the following procedure to configure a RealPort device for a printer. Note: The PortServer and RealPort should be properly installed, configured and functioning before connecting a printer. Procedure 1. Connect a proper cable between the port and printer. 2.

4. If you are using 8-pin RJ-45 cabling from the PortServer to the terminal, set the port to altpin=on by entering this command at a PortServer root prompt: set port altpin=on ra=16 This example sets altpin=on for port 16 of a PortServer. 5.

12. To configure dial-in logins on the modem port, you must have a port monitor running. You can use an existing port monitor or add a new one. This example assumes that you will add a new one. Run sysadm and choose Device, Port, Port Monitor, and then Add. Use the defaults (just press enter) for all the prompts except "Port monitor tag"...
Transparent Printer Setup About Transparent Printing Most terminals have an auxiliary port that can be connected to a serial printer. When this port is configured as a transparent printer port, print jobs may be run simultaneously with normal terminal operation. Data bound for the printer is preceded by a terminal escape sequence which turns on transparent printing, and followed by a sequence which turns transparent printing off.
Setting TTY Options The RealPort DG/UX device driver package includes a command, stty-ncxa, which is a superset of stty, and may be used to set and display the device options for Digi RealPort devices. The general command format is: stty-ncxa [-a] [-n ttyname] [option(s)] [ttyname] With no options, stty-ncxa displays all Digi special driver settings, modem signals, and all standard parameters displayed by stty(1) for the TTY device referenced by standard input.

The following options are sticky—the effects continue until the system is rebooted or until the options are changed. [-]fastbaud Alter the baud rate tables to permit the use of data rates that are beyond the range supported by the operating system. See fastbaud Data Rate Mapping, on page 3-11.

onstr "s" Defines the terminal escape sequence to direct subsequent data to the transparent printer. s is a string of ASCII characters, enclosed in quotes, that command the terminal to enter transparent printing mode. An arbitrary octal character xxx may be given as \xxx.
