What information can the modem send and receive?
The modem can send and receive short-burst data streams in the form of commands, reports and text-based messages. A command is an internal instruction sent or received by the modem to perform a function. A report is list of commands that can indicate the status of the modem. A text-based message can be initiated by an operator typing in characters through the mobile data terminal or pressing an on-screen button to send text either to another operator or a central dispatch.
