The command identifier 21
Hex
can be used to read out the program records stored in the pro-
gram from the data carrier. The user must document exactly which data are to be read from
where and with what number of bytes for the respective program (see example 11 on 51).

The command identifier 22

Copying from
Head 1 to Head 2
Head 1 to Head 2
For a copy command there must be a data carrier in front of both read/write heads (even if
dynamic mode is configured). Simultaneous data transmission is used to read (even if si-
multaneous data transmission is not configured). The total process is controlled with the
bit header(s) for Head 1. The start address and number of bytes applies both to reading at
Head 1 and to writing at Head 2. The copy command is in principle the same as reading
with simultaneous data transmission. In addition, the data which are placed in the input
buffer are written at the same time to the data carrier at Head 2.

The AE bit is not set until the write procedure at Head 2 has finished successfully. If the
GR bit is set during a started copy command, both read/write heads are placed in the
base state and the pending job is aborted (see example 8 on 45).
