IBM 4400 manual Ptrsetup Option

B PTR_SETUP Option

Overview

The PTR_SETUP commands are a superset of commands which allows the printer to perform several tasks by parsing commands either stored in flash or sent to the printer by the host. Commands range from re-routing debug statements to downloading complete printer configurations.

The PTR_SETUP Commands

Some concepts to keep in mind are as follows:

1.PTR_SETUP commands are not emulation specific. In a system with an IGP**, the IGP level emulation will process the PTR_SETUP commands. In a system without an IGP, the PTR_SETUP commands will be processed by the base emulation. The CTHI emulation will not process PTR_SETUP commands.

2.Since there is no disk on a flash-based printer, DISK_IO commands are now called FILE_IO. However, for backwards compatibility DISK_IO and FILE_IO are synonymous.

3.The PTR_SETUP command set is case sensitive; all PTR_SETUP commands are in upper case characters only.

4.The white space separating commands may be any number of spaces and tabs. This allows a PTR_SETUP file to be formatted for easier readability.

5.Any unknown command will terminate the PTR_SETUP processing. The offending command will be the first line of printed text.

6.Although the original implementation of PTR_SETUP allowed for only a single parameter, separated from the sub-command by a single semicolon (;) character, the new PTR_SETUP command set allows for multiple parameters separated by commas, semicolons, spaces or tabs.
