Appendix , Flow Control Templates.
Working with RA
and NVRAM
You can change any setting just for the current session. For example
setting your Courier V.Everything modem to
AT&N8
will only allow a
connection to a remote devices at a rate of 14400 bps or lower until the
modem is reset. Once the modem is reset, the default variable connectio
rate will be re-established.
If you want the new setting to be a default, write it to NVRAM at the
same time. From the example above, you would send
AT&N8&W
to the
modem. The new default setting for your Courier V.Everything modem
will only allow a 14400 bps connection to a remote device.
To restore NVRAM factory defaults, use the AT&Fn command. See
Appendix B,
Alphabetic Command Summar
, for more information on
setting &Fn.
