Restart the Handy
Programmer (Quit)
Sending the Restart command causes a telegram in process to be aborted and puts the
Handy Programmer in the ground state.
After this telegram is acknowledged, a minimum of 1600 ms pause should be allowed
before starting a new telegram.
Important! The Quit command is not permitted while the Handy Programmer is waiting for a
terminator (BCC or 'CR'). In this situation, the Quit would be incorrectly interpreted as a termina-
tor or datum.

Initialize a data carrier for CRC_16 data checking
This telegram initializes a data carrier located at the active read/write head for use of CRC_16 data checking.
This telegram must also be send again if a CRC error results from a failed write operation, i.e., the data carrier must be
reinitialized in order to use it again.
Please note the table on
10!
The indicated number of usable bytes may not be exceeded, i.e., the sum of start address
plus number of bytes must not exceed the data carrier memory capacity!
