Something that commands need to include when being sent to the JNIOR is the termination string. For example, if your connecting to the JNIOR using Cinema the default termination string is \\r\
. So when you send the JNIOR a command in Cinema, make sure the command ends with \\r\
. To check what termination string you need for your connection, based off the application your using on the JNIOR, you can check in the application registry keys in the JNIOR registry of a JNIOR's web page. (appdata/application name).
