/*
 * Country code first byte, then manufacturer is last two bytes. See T.35.
 * Apparently Germany issued some manufacturer codes before the two-byte
 * standard was accepted, and so some few German manufacturers are
 * identified by a single manufacturer byte.
 *
 * T.30 5.3.6.2.7 (2003) states that the NSF FIF is transmitted
 * in MSB2LSB order.  Revisions of T.30 prior to 2003 did not 
 * contain explicit specification as to the transmit bit order.
 * (Although it did otherwise state that all HDLC frame data should
 * be in MSB order except as noted.)  Because CSI, TSI, and other
 * prologue frames were in LSB order by way of an exception to the
 * general rule (T.30 5.3.6.2.4-11) many manufacturers assumed that
 * NSF should also be in LSB order.  Consequently there will be
 * some country-code "masquerading" as a terminal may use the
 * proper country-code, but with an inverted bit order.
 *
 * Thus, country code x61 (Korea) turns into x86 (Papua New Guinea),
 * code xB5 (USA) turns into xAD (Tunisia), code x26 (China) turns
 * into x64 (Lebanon), code x04 (Germany) turns into x20 (Canada), 
 * and code x3D (France) turns into xBC (Vietnam).
 *
 * For the most part it should be safe to identify a manufacturer
 * both with the MSB and LSB ordered bits, as the "masqueraded" country
 * is likely to not be actively assigning T.35 manufacturer codes.
 * However, some manufacturers (e.g. Microsoft) may use MSB for the
 * country code and LSB for the rest of the NSF, and so basically this
 * table must be verified and corrected against actual real-world
 * results.
