Report error to
the iTNC
FE1 mode is set.
If an error occurs at a peripheral device, the following block must be sent to
the iTNC:
<SOH><Error text><ETB>BCC
The received error message is displayed on the iTNC. To continue
Press the CE key.
Request external
directory
FE1 mode is set.
This protocol is not available in the EXT mode. In FE1 mode the following
Escape sequence is sent to request the external directory:
<DC3><ESC><DC1><0><SP><D><CR><LF>
The iTNC expects the following input to this request:
xxxxxx<Code letters><Sectors><Name><P
1)
><CR><LF>
1)
P = Protected (optional)
The first four lines, each ending in <CR><LF>, are ignored. In subsequent
lines ending with <CR><LF>, the program name and, after any number of
blank characters, the number of sectors are stored.
If the character combination <FREE:> is detected, only a number—the
number of free sectors—will be read in.
The iTNC requests the complete directory. The directory is saved and the files
of the selected type are displayed.
The peripheral device ends transmission with <EXT>. The iTNC sends an
<EOT>.
Output selected
file
Output marked
files
Marked files are output in the same protocol as for outputting the selected
files. After each file, the control characters <EXT><EOT> are sent to the
peripheral device.
