The protocol specifications information given in this chapter is intended to
assist those who wish to create a personal communications software package
that is compatible with the protocols used by the SDI port in the
Small System.
Note: Not all XModem CRC protocols are identical. Some may not
operate properly with the CCBR feature. Ensure that your
communications package complies to the protocol specifications
outlined in this chapter.
XModem transmission medium level protocol is asynchronous, 8 data bits no
parity, one stop bit. It allows the sending of all types of data including binary,
which is the data type used with the Customer Configuration Backup and
Restore (CCBR) feature.
