ETHERNET PRINT SERVER

For UNIX systems that use the lpr spooling system, delete the entry for the printer in the “/etc/printcap” file. You also may want to delete the entry for the printer in the RTEL directory.

7.8 Creating RTEL Pseudo-Devices

For each RTEL pseudo-device you wish to create, the EPS must execute the rteld command. The command tells the host which EPS and service to use and specifies any options to apply to the tty device pair. Options provide control over the service and host to connect to, the device to use, etc. A short synopsis appears in Table 7-1.

Running the rteld command with the startup (-s) option at system boot time will read each device entry from the server_hosts file and create an rteld process for it. Each device is specified with the server and service/port to connect to, an optional password, and any rteld command line options. For example:
