5.3.6 Pioneer LDP Protocol Driver
Media Pro Control Language Statements SEM and ICM driver for PIONEER LDP V4400
Note: This summary assumes that the user is familiar with the Pioneer Laser Disk Player, and its
control messaging. Note that not ALL features of the Pioneer LDP V4400 are accessible with
MPCL statements.
The form of the output from the driver is given in brackets, e.g.: The initialization string is
[FRPA]. All commands are terminated with <CR>, so this is not listed.

features.
