S-Registers (3Com)
Register Function (3Com) 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) 1-255 7
