Description:
With this command, the following n bytes are transmitted to the sub-
channel. The ND69 has only the sub-channel 0, which is the V.24
interface for connection to the customer display.
The data transmission is transparent, i.e. the n bytes can have arbitrary
values, which means they may also contain control commands (for the
customer display).
Remarks:
No data are transmitted from the customer display to the host
computer. After switching on, the customer display transmits data (ID).
These can be printed during the self test.

Open first cash drawer,
m = 1:
Open second cash drawer.
n1 * 10ms
