player’s RAM.

70)
PROGRAM READ
Function:
Transmits program data
Format:
Data Length
*D
Explanation:
When this command is entered, the player transmits the contents
of RAM. The data transmitted is the length indicated by the
argument and transmission begins at the address defined by the
Set Program Pointer.
The data length can be set from 0 to 64. A unit length is one byte.
Since the output data format is ASCII-HEX, each command is two
bytes so the actual length of data is twice as long as the
commands entered. (A program of 20 commands is 40 bytes
long.) Also the end of the data string terminator <C/R> is
attached.
