Configurations: Asynchronous DCE, Asynchronous DTE
Asynchronous DCE
If the second asynchronous DCE enhancement board is installed, this option enables you to set the
following options:
Both ports = B (Default)
Port 1 only = 1
Port 2 only = 2.
The setting of this option determines which port's options are displayed and which port any changes
will affect. The default value is B to facilitate the identical setting of options in both ports at hosts in
computer centers.
When the option is set to B, port 1 is displayed, but changes are stored for both ports 1 and 2. If
the option is set to 1 or 2, values will be displayed and changed for only that port.
Asynchronous DTE
The Multispeed option determines how the 7500 will react to speed change requests sent over the
EIA speed leads (pins 12 and 13).
If set to 1, the 7500 will ignore the leads and remain the speed to which it's set. If set to 2, the 7500
will support 2-speed modems and will drop to the lower speed on request. If the option is set to 3, the
7500 will support 3-speed modems and will drop to the middle or lower speed on request. The exact
