Result Codes: CONNECT – Reported when the modem begins the training sequence after
receipt of a valid <mod> value.
ERROR – If the modem transmit buffer becomes empty and the last
transmitted character is NUL (00), the modem continues to transmit NULs
until the DTE sends more data or five seconds elapses. After five seconds
elapse with an empty transmit buffer, the modem will turn off the transmit
carrier, return to the command state, and report the ERROR result code.
OK – If the modem’s transmit buffer becomes empty and the last transmitted
character is not NUL, the modem will turn off the transmit carrier, return to the
command state, and report the OK result code.
