Hardware Flow Control Template

&F1
When the Total Control MP is first turned on, the modems
automatically load the hardware flow control template into
active RAM from Non-Volatile Random Access Memory
(NVRAM). The Hardware Flow Control template, though
stored in ROM, is also stored in NVRAM as the current settings.
Unless a modem is programmed for another template, it will
operate under this configuration.
In this configuration, the modems are set to operate with
hardware flow control, a fixed serial port rate using the highest-
level result codes.
The modem drops the Clear to Send (CTS) signal it has been
sending to the computer or terminal when the modem's buffer
nears 90% capacity. It starts sending CTS again when the buffer
is about half full.
Table 3.1 on the opposite page shows the configuration
command settings under the hardware flow control template.
Recommended Uses
This template is the most compatible and is recommended for
all systems and software that support Request to Send and
Clear to Send hardware signaling, and a fixed serial port rate to
provide flow control. It offers the greatest efficiency and
reliability. If your system requires software flow control, your
best bet is to use the Software Flow Control template described
next.
If your system supports hardware flow control, you may wish
to review the descriptions of the other templates, or go directly

Accessing the Modems
