Definite-length block response data
Definite-length block response data allows any type of device-dependent data
to be transmitted over the system interface as a series of 8-bit binary data
bytes. This is particularly useful for sending large quantities of data or 8-bit
extended ASCII codes. The syntax is a pound sign ( # ) followed by a
non-zero digit representing the number of digits in the decimal integer. After
the non-zero digit is the decimal integer that states the number of 8-bit data
bytes being sent. This is followed by the actual data.
For example, for transmitting 4000 bytes of data, the syntax would be:
The “8” states the number of digits that follow, and “00004000” states the
number of bytes to be transmitted.
