Using LPD Your Terminal Server can be setup for receiving print jobs via LPD and this is a very simple method. It works for both Windows ® and Unix systems. Configuration The following fields are important: Terminal Server User Guide Chapter 8 Printing Using LPD Page 99...
Page 100 Field Description Flow control Set your Terminal Server port flow control to Hardware. Then set your printer to use ‘DTR Pacing’ or ‘Hardware’ or ‘Ready/ Busy’ flow control. Use the RS-232 printer cable pinout shown in the Cabling Guide (Appendix C), as this will save a print job if the printer is turned off or the cable becomes detached.
Page 101: Accessing The Printer
Accessing the Printer The client is the machine that contains the file to be printed and may be running one of a range of operating systems and applications. The client must support LPD, Unix systems normally include a version of LPD and there are a number of TCP/IP applications for DOS/ Windows ®...
Page 102: Lpd Printing From Dos/Windows
LPD printing from DOS/Windows ® At present it is possible to print from Windows ® or DOS although this will normally be accomplished via a separate application program like PC/TCP or Netmanage Chameleon. The new versions of Windows ® type operating systems either have or intended to have TCP/IP built into the operating system.
Page 103: Lpd Printing From Bsd Unix And Linux
LPD Printing from BSD Unix and Linux This section should give you some idea of how to set-up printing via LPD on a Unix host. However, this will not be universally true as different versions of Unix have different configuration requirements. You may also wish to consult your Operating System documentation before attempting to add LPD.
Page 104: Lpd Printing From Sys V Unix
This would be sufficient to print a header page and perform form feeds. If a specialised filter program is required for something like a plotter then the script may look something like the following: #!/bin/sh /usr/local/filter ‘$@’ | lpr –PLaser1 LPD Printing from SYS V Unix Here is an example for setting up the System V spooling system (for example, Linux, Solaris, etc.) to print to the Terminal Server LPD daemon.
Page 105: Using Rcp
Using RCP RCP is used as an alternative option (where LPD and ioland are not available). It is a Unix only command set. A script is provided on the CD for RCP. Configuration The following fields are important: Field Description Flow ctrl Set your Terminal Server port flow control to Both.
Page 106: The Host
Field Description Mode The port of the terminal server will operate in a raw TCP/IP mode. Local port The INETD process running on the terminal server for this port is listening for TCP/IP connections on TCP port 514 (this is the RCP service number). The Host On systems where LPD or a binary for ioland is not available, or is found to be unreliable due to limitations in the OS, RCP provides a useful, if limited, alternative method for printing.
Page 107: Using Rcp With Unix System V Line Printer Spoolers
Using RCP with Unix System V line printer spoolers. 1. Log in as root and create a print queue for the printer with /dev/null as the device port. For example, create an HP LaserJet printer queue via the command: /usr/lib/lpadmin -hpjet -v/dev/null -mHPLaserJet Do not accept or enable the printer at this stage.

Page 112: Reverse Telnet Port Configuration
Reverse Telnet Port Configuration This setup is used when you need to access a serial port from the network. For example you might want to collect data from a serial device such as a barcode scanner, POS terminal, etc. Or you can tie a login to a specific Unix tty device (using ioland). For Unix you use the utility ioland.
Page 113: The Host
The Host If you are already familiar with ioland, all you have to do for the above configuration on Unix ioland -p <server name> 10006 <device name> This will start the ioland process in permanent mode and create a device in /dev. If you are not familiar with the ioland program, read the following section.
Page 114: Black Box Ioland Utility
Black Box IOLAND Utility The Terminal Server peripheral daemon provides a client process with a full-duplex and transparent interface to a server port of its choice, via a pseudo-tty device. This presents a tty-like interface to the application in much the same way as a serial port.
Page 115: Mandatory Arguments
This should be used as the interface device for client processes since the pseudo-tty may change during the daemon lifetime. Terminal Server User Guide Chapter 9 Other devices setup Black Box IOLAND Utility Page 115...

Page 120: Tips
Tips Unix Notes On Unix variants based on System V Release 3, clients that are interactive shell processes may not be able to handle the interrupt, quit and break keys properly. This is a deficiency in the pseudo-tty drivers and not the daemon. On some System V Release 4 variants, if the daemon writes to a non-existent client, the pseudo-tty may irretrievably hang up.

Page 176: Terminals/Pc Problems
Terminals/PC Problems If your terminal or PC connection is not working properly, symptoms are usually no output at all, 'garbage' on the screen, loss of characters or ports locking. Here is the common solution checklist to these problems: Problem Action required Cable error Replace the cable with a known good one or test the cable ends.
Page 177 Problem Action required Electrical noise If your equipment (especially cables) is near any high voltage equipment it may be picking up electrical noise which is corrupting the data signals. Check the stats screen of the unit (check Line Stats for malformed characters). Ensure all cables are correctly screened and attempt to keep them away from high voltage equipment.
Page 178: Printer Problems
Printer Problems You can check some of the same problem notes in the terminal section because most are applicable to printers. The main problem is with cabling. Problem Action required Testing the port If you experience printer problems, it’s a good idea to temporarily connect a terminal in place of the printer so you can ensure some of the basic functions are working correctly.
Page 179 Problem Action required Spooler problems Test the printer without relying on your spooler by sending data direct to the port you created and named when you ran the ioland daemon. Do this by typing: cat data_file > /dev/laser1 If this command returns, then the Unix system believes it has sent the data and there is a good chance it has been printed successfully.
Page 180: Modem Problems
Modem problems Check some of the same problem notes in the terminal section because most are applicable to modems. The main problem here is also cable problems and port setup. Problem Action required Testing the port The first thing to ascertain is that you can talk to the modem. Check this by telneting to the port and attempting to obtain a response from the modem.
Page 181: Unit Still Does Not Communicate
Unit still does not communicate A situation may occur which causes the unit to completely not function. Here are possible problems Problem Action required Port locked Try killing the port as it may be locked due to some situation that is no longer obvious. Also, killing the port ensures that any changes in the configuration will be acted upon.
