+ * serial.c (serial_ops_p): New typedef.
+ (serial_ops_list): Now a VEC.
+ (serial_interface_lookup): Return const. Use VEC_iterate.
+ (serial_add_interface): Make parameter const.
+ (serial_open): Update.
+ (serial_fdopen_ops): Make 'ops' const.
+ (serial_pipe): Update.
+ * ser-tcp.c (_initialize_ser_tcp): Update.
+ * ser-pipe.c (_initialize_ser_pipe): Update.
+ * ser-unix.c (_initialize_ser_hardwire): Update.
+ * ser-mingw.c (_initialize_ser_windows): Update.
+ * ser-go32.c (dos_ops): Now const. Update.
+ * serial.h (struct serial) <ops>: Now const.
