Ampersand (&) Command Set
B-7
&H1
Use hardware flow control. Requires that your
computer and software support Clear to Send
(CTS) at the EIA-232 interface.
&H2 Use software flow control. Requires that your
software support XON/XOFF signaling.
&H3 Use both hardware and software flow control. If
you are unsure about what your equipment
supports, select this option.
&In Received data software flow (XON/OFF) control.
&I0
Disables XON/XOFF flow control of received data.
&I1 The modem acts on your typed XON/XOFF
commands, Ctrl-S or Ctrl-Q, and passes them to
the remote device.
&I2 The modem acts on your XON/XOFF commands,
but removes them from the data stream instead
of passing them to the remote device. This is the
recommended setting for ARQ mode.
&I3 Hewlett Packard-Host mode. Applies only to
modems attached to an HP mainframe that uses
the ENQ/ACK protocol. Use in ARQ mode only.
&I4 Hewlett Packard-Terminal mode. Applies only to
modems attached to terminals in an HP system
that uses the ENQ/ACK protocol. Use in ARQ
mode only.
&I5 This setting is designed to enable flow control on
the phone link when the connection is not under
error control. For this to work, the remote device
must have &I5 capability.
&Kn Enable or disable data compression.
&K0 Disable data compression.
&K1
Use auto-enable/disable. The modem enables
compression if the serial port rate is fixed (&B1)
and disables compression if the serial port rate
follows the connection rate (&B0) because
compression offers no throughput advantage
when the serial port and connection rates are
equal; in fact, compression may degrade
throughput.
&K2 Always enable data compression.
