Command
Function (3Com, US Robotics)
&W1
Store user profile 1 to memory

Register
Function (3Com, US Robotics)
Range
Default
S0
Number of rings before the modem auto-answers a call (0 means auto-
answer is disabled and manual answer is in effect)
0-255
0 rings
S1
Counts and logs the number of rings
0-255
0 rings
S2
Designates the ASCII character used to indicate an escape character
0-127
43
S3
Designates the ASCII character used for carriage returns
0-127
13
S4
Designates the ASCII character used for line feeds
0-127
10
S5
Designates the ASCII character used for backspaces
0-127
8
S6
Dial tone wait time; if AT command X is set to X2 or X4, the modem
ignores this register and dials as soon as it detects a dial tone (seconds)
2-255
3
S7
Carrier wait time (seconds)
1-255
60
S8
Pause in dialing time (comma in dialing string) (seconds)
0-255
2
S9
Carrier detect validation time (1/10 second)
1-255
6
S10
Delay time between lost carrier and hang up; if S10=255, the modem
will not hang up when the carrier is lost; dropping DTR hangs up the
modem (1/10 second)

S12
Guard time for the escape code (1/50 second)
0-255
1
S13
