serial: fix parity for inverse coding convention Important note: it is my (Mother Mychaela's) understanding that SIM cards with inverse coding convention are extremely rare, and I have never seen such a card. Therefore, our support for the inverse coding convention will likely remain forever untested.

/* extern definitions for global vars defined in curfile.c */

extern unsigned curfile_total_size, curfile_structure;
extern unsigned curfile_record_len, curfile_record_count;
