&C DCD Control
The AT&C command is used to configure the way in which the unit controls the DCD signal
to the terminal. There are three options:
&C0 DCD is always On
&C1 DCD is On only when an ISDN connection has been established (Layer 2 is UP)
&C2 DCD is always Off
&C3 DCD is normally On but pulses low for a time in 10 msec units determined by S register
10.
&F Load Factory Settings
The AT&F command is used to load a pre-defined default set of S-register and AT command
settings (the default profile). These are:
E1, V1, &C1, &K1, &D2, S0=0, S2=43
All other values are set to 0.
&R CTS Control
The AT&R command is used to configure the way in which the unit controls the CTS signal
to the terminal. There are three options:
&R0 CTS is always On
&R1 CTS follows RTS. The delay between RTS changing and CTS changing is set in AT
register 56 in multiples of 10msec
&R2 CTS is always Off
&V View Profiles
The AT&V command displays a list of the current AT command and S register values, and
the settings for the two stored profiles. For example:
at&v
CURRENT PROFILE:
&c1 &d2 &k1 &s1 &r0 e1 q0 v1 &y0
S0=0 S2=43 S12=50 S31=3 S45=5
states DTR:1 RTS:1
STORED PROFILE 0:
&c1 &d2 &k1 &s1 &r0 e1 q0 v1
S0=0 S2=43 S12=50 S31=3 S45=5
STORED PROFILE 1:
&c1 &d2 &k1 &s1 &r0 e1 q0 v1
S0=0 S2=43 S12=50 S31=3 S45=5
OK
&W Write SREGS.DAT
The AT&W command is used to save the current command and S registers settings (for the
active port), to the file SREGS.DAT. The settings contained in this file can be reloaded at
any time using the ATZ command.
