whether the IP Modem is in command or in data mode. When set to 
always on by AT&S0 (this is the default) the DSR may have a separate 
source. The DTR is free to serve as a DCD to the PC. The operation of 
DCD is defined by AT&C, so these commands are related. An AT&S1 
has DSR follow the data mode. 
The  AT&C has priority over this command. AT&S1 can only be 
effective, if AT&C0 is set.

Understand the DTR signal of the PC. The input on the IP Modem is 
the DSR, which requires a proper serial cable. Usually this signal is 
either ignored, or serves to disconnect from the phone line. There are 
four options: 
 AT&D0  Ignore DTR from PC 

 

 AT&D1  Toggle DTR to enter command mode

AT\Q1 configure for XON/XOFF Software Flow Control between PC 
and IP Modem. Other Options are not supported.

profile, the short dial strings and the factory profile. Parameters are 
accepted but ignored. AT&V is AT&V0 and is AT&V1. 
8.1.5.21. 

Save the current configuration as user profile. AT&W is the same as 
AT&W0, all other commands report an ERROR.

This command will save a destination in internet syntax. It is given by 
<host>:<port>. The <host> is either an IP-Address in dotted octet
