5. CONTROL PORT OPERATION

The HTU-C M R provides a faceplate-mounted DB9
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.
Operation
For abbreviations used in the screen diagrams, see
Table 6.
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.
