^HW

Host Directory List

Description: ^HW is used to transmit a directory listing of objects in a specific

memory area (storage device) back to the host device. This command will return a

formatted ASCII string of object names to the host.

Each object is listed on a line and has a fixed length. The total length of a line is also

fixed. Each line listing an object begins with the asterisk (*) followed by a blank

space. There are then eight spaces for the object name, a period and three spaces for

the extension. The extension is followed by two blank spaces, then six spaces for the

object size, two blank spaces and three spaces for option flags (reserved for future

use). The format looks like this:

DIR R: <CR><LF>

*Name.ext(2sp.)(6 obj. sz.)(2sp.)(3 option flags)

-xxxxxxx bytes free

<ETX>

<STX> = start of text

<CR><LR> = carriage return/line feed

<ETX> = end on text

The command may be used in a stand-alone type file to be issued to the printer at any

time. The printer will return the directory listing as soon as possible, based on other

tasks it may be performing when the command is received.

This command, like all ^ (caret) commands, is processed in the order that it is

received by the printer.
