Fixed now, I believe.
The problem is that the LaserJet 2100 was sending error messages like:
@PJL USTATUS TIMED
CODE=41900
...
and a comment in ifhp.c implies that the second line "may" be a value for
the variable at the end of the first. I'm not a PJL expert, nor have I
looked at the PJL documentation, but it seems to me a reasonable
assumption that if the second line has an "=", it's not a value. (Please
correct me if I'm wrong!)
In our case, I fixed this by moving the eq_line check up a bit, so that
the second line gets processed on its own in addition to being appended
to the first:
*** ifhp.c.orig Wed Apr 17 19:13:47 2002
--- ifhp.c Wed Apr 17 18:51:09 2002
***************
*** 733,738 ****
--- 733,739 ----
* last entry may be a variable name and the next
* line a value for it. We need to append to the variable value
*/
+ eq_line = safestrchr( str, '=' );
pjlline = !safestrncasecmp( str, "@PJL",4);
if( pjlvar ){
if( !pjlline && !ISNULL(str) ){
***************
*** 755,761 ****
SAFEFREE(pjlstatus); pjlstatus = 0;
pjlinfo = 0;
}
! if( !pjlline ) goto done;
}
if( (ps_str = safestrstr( str,"%%[" )) ){
--- 756,762 ----
SAFEFREE(pjlstatus); pjlstatus = 0;
pjlinfo = 0;
}
! if( (!pjlline) && (!eq_line) ) goto done;
}
if( (ps_str = safestrstr( str,"%%[" )) ){
***************
*** 766,772 ****
c = cval(s);
*s = 0;
}
- eq_line = safestrchr( str, '=' );
if( s ) *s = c;
/* now we check for xx=value entries */
