This will let you send a CBM DOS command over the disk drive command channel. You will se a '@' character at the bottom of the screen along with the device number you will be using. The useful commands are as follows:
C0:newfile=oldfile
Copy a file on the same disk.
I0
Initialize disk.
N0:diskname,ID
Format (header, new) disk, use with caution.
R0:newfile=oldfile
Rename a file.
S0:filename
Scratch (delete) a file.
UJ
Reset disk drive.
U0>M0
Force drive into 1541 mode (1571 only)
U0>M1
Put drive into 1571 mode (1571 only)
U0>H0
Select head 0 (1571 in 1541 mode only)
U0>H1
Select head 1 (1571 in 1541 mode only)
U0>V1
Write verify OFF (1571 with new ROM & 1581)
U0>V0
Write verify ON (1571 with new ROM & 1581)
V0
Validate disk. PLEASE NOTE: This command has been enhanced. Unlike the standard validate command, it will protect boot sector(s), if present, from being overwritten later. Please note that the boot-protect won't work with drive 1 in a dual drive unit.
/0:partition
Change disk partition (1581 only).
/
Change to root directory (1581 only).
Please refer to your disk drive manual for a more thorough description of the above commands.
Extra DOS commands:
#number
Change/swap device number. Typing '#' followed by a number between 4 and 29 will change the device address of the current disk drive to that number. If the device number specified is used by another disk drive, the two drives will swap device numbers. DO NOT use this command if there's currently a disk drive active on the serial bus with device number of 30. Device number 30 is used temporarily as the device numbers are swapped. Also, you can NOT swap devices with printers or other non-disk units. It will work fine with RAMDOS though.
After a DOS command has been performed, the drive status will be displayed. You can press RETURN without entering a command if you only wish to view the the drive status. Please refer to your disk drive manual for interpretation of the status messages.
You may recall the last DOS command by pressing SHIFT/RETURN while the cursor is flashing on the DOS command line. Please note that this feature is only effective as long as you stay within THE SERVANT. If you exit, and then re-enter THE SERVANT, any previous commands is erased.
