Select
NRZ
(typically used in the U.S.) or
NRZI
(typically used in Europe) for the encoding used on
your SDLC line.
This value must match the encoding scheme used by
the modem at the remote end of the link. If you set this
field incorrectly, you will find that the frames being
received are all discarded and do not appear in any
trace.
On a VTAM host, this is the NRZI= setting in the
LINE/GROUP definition.
For switched outgoing ports, you configure the line
encoding on each link station (see “Defining Link
Stations”) instead of on the port.
On some platforms, if you configure a switched
incoming port, you need to configure the following:
Dial string
An ASCII string to be sent to your modem in order to
prepare it to accept incoming calls.
By default, the dial string is sent to the modem at the
rate of 1200 bits per second (the default baud rate)
using asynchronous communications. You can match
the baud rate to the modem's baud rate by placing one
of the following numbers, enclosed by parentheses, in
front of the dial string:
•
1
(300 baud)
•
2
(600 baud)
•
3
(1200 baud)
•
4
(2400 baud)
•
5
(4800 baud)
•
6
(9600 baud)
•
7
(19200 baud)
For example, you can specify a 9600 baud rate dial
string by entering
(6)
, as follows:
(6)AT &&D3 &&Q1 DT7,012345678
For an explanation of the rest of the dial string, refer to
your modem's documentation.
For switched outgoing ports, the dial string is
configured on each link station. For leased ports, this
field does not apply.
