If necessary, use the set command to set your Monitor's prompt to "PMON> ". Crossview is hardwired to expect that string, and will not work with any other value (note the space after the ">").
Compile and link modules with the -g option. This will generate the .abs file that is required by Crossview. For example,
pmcc -g -o bubble bubble.cInvoke Crossview,
% xvw3r bubble.abs -i -E /dev/tty1 -S 9600 Unix C> xvw3r bubble.abs -i -E com1 -S 9600 MSDOS -- this includes downloading of bubble.abs xvw> e main -- view main xvw> 26 b -- set bpt at line 26 xvw> R -- reset target & run xvw> C [bpt] -- continue xvw> S -- single-step over procedures xvw> s -- single-step into procedures xvw> p->pri -- display value of p->pri xvw> B -- display bpts xvw> 0 d -- delete bpt 0 xvw> D -- delete all bpts xvw> o [cmd] -- enter transparent mode. exit with ^D xvw> Si/si -- single step machine instruction xvw> q -- quit
