ROSE has been described by Tom Moulton W2VY in different ARRL Computer
Networking Conference proceedings available on CDs (google ROSE W2VY).
Sorry I only have 3rd (1984), 9th (1990) and 13th (1994) books
without ROSE
protocole descripion.
ROSE adressing follows the X.121 specs and uses 14 digits.
There is a good description here :
http://www.rhyshaden.com/x25.htm
Linux kernel source provides diagnostic codes and specs.
For example in /linux/include/net/rose.h :
#define ROSE_ADDR_LEN 5
#define ROSE_MIN_LEN 3
#define ROSE_GFI 0x10
#define ROSE_Q_BIT 0x80
#define ROSE_D_BIT 0x40
#define ROSE_M_BIT 0x10
#define ROSE_CALL_REQUEST 0x0B
#define ROSE_CALL_ACCEPTED 0x0F
#define ROSE_CLEAR_REQUEST 0x13
#define ROSE_CLEAR_CONFIRMATION 0x17
#define ROSE_DATA 0x00
#define ROSE_INTERRUPT 0x23
#define ROSE_INTERRUPT_CONFIRMATION 0x27
#define ROSE_RR 0x01
#define ROSE_RNR 0x05
#define ROSE_REJ 0x09
#define ROSE_RESET_REQUEST 0x1B
#define ROSE_RESET_CONFIRMATION 0x1F
#define ROSE_REGISTRATION_REQUEST 0xF3
#define ROSE_REGISTRATION_CONFIRMATION 0xF7
#define ROSE_RESTART_REQUEST 0xFB
#define ROSE_RESTART_CONFIRMATION 0xFF
#define ROSE_DIAGNOSTIC 0xF1
#define ROSE_ILLEGAL 0xFD
ROSE packets identified by listen have PID=1(X.25)
Here is a sample screen dump from F6BVP FPAC node F6BVP-11 :
