COURIER HIGH SPEED MODEMS
4-32 Data Mode Operations
&ZC=s Write the following command string s to NVRAM. The
command string may be up to 30 characters long; spaces are not
counted. This command can be used so that you can call
another modem without loading your communications
software.
After storing a command, you can program the voice/data
switch to execute the stored command string when pressed.
The following example assigns a command string that displays
the link diagnostics screen when you press the voice/data
switch.
AT&ZC=I6 <Enter>
The function of the voice/data switch is determined by the set-
ting of Register S32, as described in Appendix G. Set the
voice/data switch function to execute stored command string by
setting Register S32 to 9 with the following command:
ATS32=9 <Enter>
Note that you can reset the voice/data switch at any time to one
of the other available functions. Additionally, you can
overwrite the stored command string with a new one at any
time.
Once you've stored your command string and set Register S32,
all you need to do is press the voice/data switch whenever you
want the command string executed.
&ZC? Display the stored command string.
%T Enables the modem, when off hook, to detect the tone
frequencies of dialing modems. %T is meant primarily for use
with network applications, but may also be integrated into
certain software programs. For example, %T could be used in a
security program to identify incoming tone security codes.
To enable %T, type ATH1 <Enter> to force the modem off hook.
Then type AT%T <Enter>.
To return the modem to Command mode, press any key or
drop the computer's or terminal's DTR signal. The modem
responds OK.
