496 * Country code first byte, then manufacturer is last two bytes. See T.35.
497 * Apparently Germany issued some manufacturer codes before the two-byte
498 * standard was accepted, and so some few German manufacturers are
499 * identified by a single manufacturer byte.
500 *
501 * T.30 5.3.6.2.7 (2003) states that the NSF FIF is transmitted
502 * in MSB2LSB order. Revisions of T.30 prior to 2003 did not
503 * contain explicit specification as to the transmit bit order.
504 * (Although it did otherwise state that all HDLC frame data should
505 * be in MSB order except as noted.) Because CSI, TSI, and other
506 * prologue frames were in LSB order by way of an exception to the
507 * general rule (T.30 5.3.6.2.4-11) many manufacturers assumed that
508 * NSF should also be in LSB order. Consequently there will be
509 * some country-code "masquerading" as a terminal may use the
510 * proper country-code, but with an inverted bit order.
511 *
512 * Thus, country code x61 (Korea) turns into x86 (Papua New Guinea),
513 * code xB5 (USA) turns into xAD (Tunisia), code x26 (China) turns
514 * into x64 (Lebanon), code x04 (Germany) turns into x20 (Canada),
