#ifndef __SMSUTILS_H#define __SMSUTILS_H/* Received SMS - we get a hex string representation of the data.   Roughly, the layout of the data is:   1 byte - length of SMS center information   1 byte - the format of the number (91 is the standard)   (length above - 1) bytes - the number, nibble-swapped and padded with an   f if needed   1 byte - properties of the message, generally we can ignore this   1 byte - length of sender number (in digits, not bytes)   variable bytes - sender number, nibble-swapped and padded if needed   1 byte - protocol identifier - can ignore this probably   1 byte - data coding scheme - again can hopefully be ignored   7 bytes - timestamp, again nibble-swapped: y, m, d, h, m, s, timezone   * timezone is in units of +15 min vs. GMT. If most sig. bit is   1, value is in units of -15 min vs. GMT.   1 byte - length of message in characters (NOT in bytes)   rest of bytes - message. if ASCII 7-bit, compacted to save space through   an encoding mechanism.
