5. CONTROL PORT OPERATION

The HTU-C provides a faceplate-mounted DB-9
connector that supplies an RS-232 interface for
connection to a controlling terminal. The pinout of
the DB-9 is illustrated in Figure 7.

The terminal interface operates at data rates from
1.2 kbps to 19.2 kbps. The asynchronous data format
is fixed at 8 data bits, no parity, and 1 stop bit. The
supported terminal type is VT100 or compatible.
NOTE
If you are using a personal computer (PC)
with terminal emulation capability, be sure
to disable any power saving programs.
Otherwise, communication between the PC
and the HDSL unit may be disrupted, resulting
in misplaced characters or screen timeouts.
