Format of Interlnk device driver header:
Offset Size Description )
00h DWORD pointer to next driver, offset=FFFFh if last driver
04h WORD device attributes (see #01647,#01648)
06h WORD device strategy entry point
08h WORD device interrupt entry point
0Ah 8 BYTEs character device name "NUL2 "
12h 165 BYTEs ???
B7h 67 BYTEs fully qualified Interlnk filename
FAh 6 BYTEs ???
100h DWORD pointer back to Interlnk filename at offset B7h
104h 8 BYTEs ???
10Ch BYTE total number of redirected drives
10Dh BYTE first local drive number (0=A:)
10Eh BYTE printer redirection (0=no, 1=yes)
10Fh BYTE ???
110h 3 BYTEs LPT1...3 status (0FFh=invalid)
113h 26 BYTEs remote drive number (0=A:, 0FEh=unused) (refer to note below)
12Dh 26 BYTEs always 0FEh ???
147h 26 BYTEs always 0FFh ???
Note: to obtain the remote drive number, subtract the value at offset 10Ch
from the local drive number before indexing into the table at 113h
(example: if local drives F, G, H are remote drives C, F, E then
the first three bytes at offset 113h are 02h, 05h, 04h)
for each instance of Interlnk, an extra device driver is loaded, but
all have the same device name NUL2
