//

// Function: Read a packet at a time from the device (standard SCSI Read)
// Type: Input; the following data is returned:
// LL LL NN NN NN NN XX XX XX ... CC CC CC CC
// where:
// LLLL is normally the length of the packet (a 2-byte
// big-endian hex value), including 4 trailing bytes
// of CRC, but excluding itself and the flag field.
// See below for special values
// NNNNNNNN is a 4-byte flag field with the following meanings:
// FFFFFFFF a packet has been dropped (?); in this case
// the length field appears to be always 4000
// 00000010 there are more packets currently available
// in SCSI/Link memory
// 00000000 this is the last packet
// XX XX ... is the actual packet
// CCCCCCCC is the CRC
//
// Notes:
// - When all packets have been retrieved successfully, a length field
// of 0000 is returned; however, if a packet has been dropped, the
// SCSI/Link will instead return a non-zero length field with a flag
// of FFFFFFFF when there are no more packets available. This behaviour
// seems to continue until a disable/enable sequence has been issued.
// - The SCSI/Link apparently has about 6KB buffer space for packets.
