Result Codes - Multitech MultiModem MT3334ZDX Owner's Manual

Result Codes

When the modem receives an AT command from the terminal or PC, it
tries to execute the command, then sends a status message to the PC or
terminal which reports the "results" of the command (hence the name
"result codes"). The MultiModemZDX Command mode provides you with
several responses, or "Result Codes" , that provide visual responses
during Command mode operation. These Result Codes are displayed on
your PC's video monitor.
