MultiModemISI Hybrid Series, ISIHP-2S/2U/4S/4U/4SD 121
Terminal Adapter AT Commands & S-Registers
Allows you to control the state of the CTS (Clear to Send) signal. Normally
the CTS signal follows the state of the RTS signal when TA is online.
&R0 CTS acts normally; that is, it follows RTS.
&R1 CTS is forced high, but still provides online
flow control.
&R2 CTS is forced high, but it drops on
disconnect for the period of time set by S10.
CTS still provides flow control when the TA
is online.
&Sn DSR Control
Values: n = 0, 1, or 2
Default: &S1 (DSR normal)
Controls the state of the DSR (Data Set Ready) signal on the RS232E/V.24
interface. A high DSR signal indicates to the computer that the TA is ready
to transmit data.
&S0 DSR is always high.
&S1 DSR acts normally; that is, it follows the
state of the CD signal, which goes high
when the ISIHP-2S/2U detects a carrier
signal, and goes low when the carrier signal
is lost.
&S2 DSR is always high, except on disconnect,
when it drops for the period of time set by
S10 and then goes high again.
&Vn View Port Configuration Parameters
Values: n = 0, 1, 2
Default: n/a
Allows you to view the port configuration parameters for ports 0 and 1.
This listing is the equivalent of both L5 and L6 combined.
&V0 Displays port 0 configuration parameters.
&V1 Displays port 1 configuration parameters.
&V2 Displays both port 0 and port 1
configuration parameters.
