OK, I believe (it has been so long, I am not certain) that the
when you replace the parameters, you merely end up specifying them in
the same order in which they come out when you are using the Tcl/Tk
interface. Thus you could grab the numbers, modify one or two of them, and
then ship the whole lot back to the drive.
For your purposes, it might make more sense to modify scsiinfo to
do the heavy lifting for you - have it first snarf the page, then modify the
appropriate bits, and then send it back again. Completely untested, but the
below might do the trick.

int frob_error_recovery_page(int page_code)
{
int status;
int bdlen;
unsigned char * pagestart;
SETUP_MODE_PAGE(1, 14);
#if 0
bitfield(pagestart+2, "AWRE", 1, 7);
bitfield(pagestart+2, "ARRE", 1, 6);
#endif
pagestart[2] |= 0xc0; /* Set bits 6 and 7 for AWRE and ARRE */
put_mode_page(1, buffer+8, 0);
return 0;
}
