As each frame is transmitted by the host computer, the computer waits for the
delimiter to be transmitted from the CPM2A/CPM2C. After the delimiter has
been transmitted, the next frame will then be sent. This procedure is repeated
until the entire command has been transmitted.

As each frame is received by the host computer, a delimiter is transmitted to the
CPM2A/CPM2C. After the delimiter has been transmitted, the CPM2A/CPM2C
will transmit the next frame. This procedure is repeated until the entire response
has been transmitted.
