The 

 command triggers a write operation (upload) and queries the amount of data already sent, but not

acknowledged at the TCP layer. The write operation may be run in binary mode, or in interactive text mode. 

The 

 write command may return the following errors: 

•

 if there is a problem on application, socket, PPP or GPRS/GSM level. The

 command and the "

" URC offer additional error information. 

•

 e.g. if the service has not network resources allocated. 

•

 e.g. if the service is not configured. 

^SISW: 

Data availability status of the Internet service configured with

the service is ready to accept new user data. 

The URC is disabled in polling mode. See

 may be 1...1500 bytes to specify the amount of data to be sent with

. 

• If parameter 

 equals 0, 

 does not expect any data, but a normal query is per-

fomed. This allows the application to explictly request, in particular at the end of an upload job, the amount of

unacknowledged data at the TCP layer indicated by 

• In interactive text mode, 

 must be set to any value greater than 0 (but not necessarily

the precise number of bytes). If set to 0 in interactive text mode, 

 would be interpreted

as query for unacknowledged data and, thus, prevent data transfer.
