Modem Connection
On page 3 of the example forms shown below, there are 11 fields that are hidden
when the
Modem Connection
field is set to none. In this example the
Modem
Connection
field is set to external, and these additional 11 fields are visible.
The first 2 fields on page 3 help setup the data format for the serial data from the
switch to the modem.There are only two valid combinations for these 2 fields:
■
Data Bits = 8, Parity = None
■
Data Bits = 7, Parity = (odd, even, mark, or space)
The remaining fields are listed below:
SPE Optional
Boards
These fields indicate whether a Disk circuit pack is present in the
system, and which Packet Interface slots are administered. If a
Packet Interface circuit pack is physically present, the corresponding
Packet Interface field is set to y when the system boots, and no
change to that field is allowed. If the system is equipped with
duplicated SPEs, a Packet Interface field is set to y when either SPE
carrier contains a Packet Interface circuit pack in the corresponding
position. If a Packet Interface circuit pack is not present, then the
value for the Packet Interface field is read from translation data
stored on disk or tape. If the field is set to n, a Packet Interface circuit
pack may be administered by changing the corresponding Packet
Interface field to y.
Modem Connection
None or external (none)
Modem Name
This field is 20 characters long and will permit alpha-numeric
characters to provide a unique qualifier for a given modem.
RTS/CTS Enabled
This field will inform the modem that communication with the data
source UART will be driven with RTS/CTS flow control. This field is
6 characters long and is case in-sensitive.
Asynchronous
Data Mode
This field will configure the modem as an asynchronous
communications device. This field is 8 characters long and is case
in-sensitive.
DTE Auto-Data
Speed
This option will adjust the speed of the data source (DTE) UART to
the outgoing (modem-to-modem) data rate. So, at maximum this
speed would be 9600 baud. This field is 6 characters long and is
case in-sensitive.
Note that this field sets the link speed between the switch and the
modem. It does not set the speed of the modem. It is not desirable
to have the serial data fill the modem buffer faster than the outgoing
data rate especially because data compression is disabled.
