10.6 AT^SISW Internet Service Write Data
AT^SISW write command triggers writing data via the Internet service configured configured with AT^SISS.

• value equal 0 indicates that the MC75 failed to enter online data mode. Details about
the cause of failure is available using AT+CEER.
• value greater than 0 indicates that the MC75 switches into online data mode to transfer
the given number of bytes.
A URC "^SISW: , " will be issued if
• the MC75 is capable to send data after opening the Internet service or
• less transmission buffer space was confirmed (in ) than requested (with ) or
