MP/8 V.34: Getting Started
The
AT
command alerts the modem that other commands
follow. The
&F2
command tells the modem to load ROM
template 2, Software Flow Control, as the active settings.
This command can be used to call up the other templates as
well—simply replace the
2
with a
0
for the No Flow Control
template, or a
1
for the Hardware Flow Control template.
The
&W
command stores the current settings to NVRAM.
This command may also be used to store any on-the-fly
changes into NVRAM. See below,
Custom Configurations.
Once the new template has been saved to NVRAM, as long as
DIP switch 10 is OFF (factory setting), the modem will load the
NVRAM settings upon booting up.
Custom Configurations
If none of the ROM templates are exactly suitable for a system,
they can be customized to fit whatever communications needs
you may have.
To custom configure a modem:
1. Change all the configurations commands and S-Registers to
fit your requirements. For example, to set the modem for
V.42
bis
data compression and pulse dialing, type:
AT &K3 P &W <Enter>
The
&W
command stores these commands as the new
current settings in NVRAM.
&W
can be used with any of
the commands in the templates to add new changes to the
settings stored in NVRAM.
2. Make sure that DIP switch 10 is OFF so the modem will
load the NVRAM settings upon booting up.
