where: YY is the last two digits of the year 1995
MM
is the two-digit month code (01-12) Nov
DD is date (01-31) 25
HH
is the hour (00-23) 6 (am)
MM is the minutes after the hour (00-59) 59
SS
is seconds (optional) 23
If you want the DSP to keep current time, either keep its power supply on, have the software program you’re using
set the clock upon start-up, or install a dedicated clock chip. The clock chip of choice is the SmartWatch clock chip
(DS1216C) by Dallas Semiconductor, 4350 Beltwood Parkway, Dallas, TX 75244. Phone: (214) 450-0400. (You
can also order the chip from JDR Microdevices, 1-800-538-5000.) The only time the SmartWatch is read is upon
power-up,
RESTART or RESET .
Installation is easy: Carefully remove U5, install the SmartWatch chip into U5’s socket, then insert U5 into the top
of the SmartWatch chip. Enter the time and date in
DAYTIME and you’re all set.

ON The DELETE ($7F) key is used for editing your typing.
OFF
The
BACKSPACE
($08) key is used for editing your typing.
Use the
DELETE command to select the key to use for “backing up” and deleting text.
Refer to

DIRect “m n” Immediate command
Host: DQ
DIRECT is an immediate command that displays a directory listing of all available DSP-232 Modems. When the
DIRECT command is given, the modem list is displayed as shown below:
The DIRECT command can also take a modem number as an arguement to display only the information on that
particular modem including the argument of 0 which displays only the date of the modem EPROM. A range of
arguments can also be entered, for example DIRECT 1 9 will display the directory of all the RTTY/TOR modems
contain in the MODEM EPROM.
