RT-11 V5 - Patching the monitor for Remote Console Line

Hiya guys, Quick question, I can't find what I'm doing wrong. I sysgen'd a XM monitor with Multiterminal Support on RT-11 V5.7: .sh conf RT-11XM (S) V05.07 Booted from DL0:RT11XM 22 bit addressing is on USR is set NOSWAP EXIT is set SWAP KMON is set NOIND RUN is set NOVBGEXE MODE is set NOSJ TT is set NOQUIET ERROR is set ERROR SL is set OFF EDIT is set KEX FORTRAN is set FORTRA KMON nesting depth is 3 CLI is set DCL, CCL, UCL, NO UCF PDP 11/94 Processor 4088KB of memory Floating Point Microcode Extended Instruction Set (EIS) Memory Management Unit 60 Hertz System Clock Device I/O time-out support Multi-terminal support UNIBUS mapping enabled Then from AA-M240E-TC - RT-11 System Generation Guide Section C-4: Assigning a Remote Line as the Console Terminal You can customize your FB, XM, and ZM monitors to allow a terminal connected through a dial-up line to be used as the console terminal. The multiterminal software will answer the line when called (provided appropriate modem hardware is in place) and connect the remote terminal to the system as the console terminal. In this customization, monitr.SYS is the name of the multiterminal monitor file that you wish to modify, and ..CRMT is the value of that symbol from the monitor link map. .RUN SIPP RET *monitr.SYS RET Base? 0 RET Offset? ..CRMT RET Base Offset Old New? 000000 ..CRMT 020000 0 RET 000000 ..CRMT+2 xxxxxx CTRL/Y RET * CTRL/C . So I find from the RT11XM.MAP that .CRMT is offset 144414: .run sipp *RT11XM.SYS Base? 0 Offset? 144414 Base Offset Old New? 000000 144414 020000 0 ?SIPP-E-Exceeds program limit Offset? System Messages Manual states: "Explanation: The location being examined or modified is beyond the end of the program. User Action: SIPP returns with the OFFSET? prompt and does not discard any previous changes. The current open location is not modified." But how can that be as the RT11XM.MAP is coming from the most recent SYSGEN? With kind regards, Obliviscor
