6.3 Port Characteristics

You can change all port settings via the SET (or DEFINE) PORT commands. Since the ports logout after each print job, you will generally want to use only DEFINE to configure them. You can LOGOUT the port to force the new settings to take effect. There are 4 basic groups of port settings that you can change:

1.Serial characteristics: baud rate, parity, flow control, and character size. The default settings are 9600, None, X-on/X-off, and 8-bit, respectively. You may change all 4, but note the warnings below under AppleTalk. Set the port speed as high as the printer will allow, especially for PostScript printers.

2.Parallel settings: you can set the type of parallel port to CENTRONICS (default) or DATAPRODUCTS. See the SET/DEFINE PRINTER command.

3.Access mode: controls who has access to the port in question. Access can be LOCAL (no network connections), DYNAMIC (either network or local serial users), or REMOTE (network users only). By default, the parallel port is REMOTE, since you cannot log into the EPS from that port. If SW2 is in the OFF position, the serial port is DYNAMIC, allowing both logins on that port and service connections from network hosts. Ports in LOCAL mode are not available as printer ports to network hosts, and thus print requests to that port will be queued or will fail. If you will be using the serial port only as a print port (and never for configuration), you will want to set the serial port to REMOTE by turning SW2 to the ON position. This will prevent any characters from the printer from being interpreted as a login attempt and thus preventing network access to the printer. If you define the serial port to be REMOTE, you must have another way (LAT, Telnet, TSM/NCP, EPSCON) to access the EPS in case of problems.

4.Print mode: if you will use the serial port exclusively for printing PostScript jobs to an interactive printer, doing a DEFINE PORT 1 POSTSCRIPT ENABLED may help prevent problems. In this mode, the EPS will attempt to confirm that the printer finished a job before accepting a new one.

6.4Service Settings

The service settings control which protocols can use the EPS’s ports and how these ports appear to the network users. In general, there has to be at least one service associated with a port before network users can use the port. (LAT and TCP/IP, the exceptions to this, are discussed in Sections 6.6 and 6.8.) Multiple services can refer to the same port, and one service can also
