7-8 Compaq AlphaServer ES40 Service Guide
After downloading binary files, you can set the com1_mode environment
variable from the SRM console to switch back to Snoop mode or other modes for
accessing the RMC, or you can hang up the current modem session and
reconnect it.
Firm Bypass Mode
In Firm Bypass mode all data and control signals are routed directly between
the system COM1 port and the external modem port. The RMC does not
configure or monitor the modem. Firm Bypass mode is useful if you want the
system, not the RMC, to fully control the modem port and you want to disable
RMC remote management features such as remote dial-in and dial-out alert.
You can switch to other modes by resetting the com1_mode environment
variable from the SRM console, but you must then set up the RMC again from
the local terminal.
