Hardware Flow Control
The Switch and Remote Modules use the CTS line for flow control.
If the hardware flow control is not enabled on the PC, or if a cable
without the CTS line connected is used, characters can be lost
when the buffer is full.
 NOTE:
The DEFINITY Extender 1100 System uses the CTS lead for flow
control. When the internal buffer is 1024 characters from full, the
CTS lead is turned off. While CTS is off, up to an additional 1024
characters can be transmitted without any loss of data. If hardware
flow control is not enabled or if a cable without the CTS lead is
used, characters will be lost when this buffer overflows.
 The DEFINITY Extender 1100 System uses the DCD lead to
indicate whether or not the modules have made a connection.
When this lead is on, the modules have made connection.
