Command 
 Refer to Table 4.10. 
Return message: 'C' Operation completed successfully
If the file to be deleted is not the last file in the sensor,  the sensor moves all the 
following files up and waits until the operation is complete. After deletion, the file 
allocation table (FAT) is updated. 
Example: $PASHS,FIL,D,5*47 (Delete 5th file in sensor)
Set Altitude-Fixed Mode
$PASHS,FIX
This command sets the altitude-fixed mode for position computation. Two modes 
define what altitude is selected when the sensor is in altitude hold mode. 
In mode 0 the most recent altitude is used. This is either the one entered by using the 
$PASHS,ALT set command or the one computed when four or more SVs are used in 
the solution, whichever is most recent. If the last altitude is the one computed with 
four or more SVs, it is used only if VDOP is less than the VDOP mask. 
In mode 1 only the last altitude entered is used in the position solution.
On initial power-up or after use of the $PASHS,INI memory reset command, or 
$PASHS,RST default parameter reset command, the most recent antenna altitude is 
zero.
The command structure is $PASHS,FIX,x where x is 0 or 1 as defined above. Default 
is 0. 
Example: Use most recently entered altitude:
$PASHS,ALT,FIX,1
Request File Information 
$PASHQ,FLS,D,C
This command requests file information within a specified range. The structure is 
$PASHQ,FLS,d,c where d is the port that received the request and c is the port to 
 Table 4.10: FIL Structure
Setting Description
999 Delete all image files in the receiver
d Index of the file to be deleted
* Delimiter between data and checksum
h Byte wise XOR checksum in hex checksum beginning  with PASHS (exclude '$' 
sign)
