IBM AS/400e Computer Hardware User Manual


 
name AS/400 has assigned to the communications port. To determine the
resource name you need, see “Hardware Requirements for the Asynchronous
Line Description” on page 128.
LINESPEED(19200)
The line speed of the asynchronous line in bits per second (bps). The line
speed you specify must be compatible with the modem attached to the line. In
this example, the line speed is set to 19,200 bps.
Note: When using a direct connection, both systems must specify the same
value for the line speed.
MAXBUFFER(1500)
The maximum size of any single data packet sent across the line. This value
must always be at least as large as the value specified for the Maximum
Transmission Unit (MTU) in any TCP/IP point-to-point profile that uses this line.
Note: The value MAXBUFFER(1500) is used in this example because the
value 1500 is larger than any MTU value that could be specified in a
TCP/IP point-to-point configuration profile.
CNN(*NONSWTPP)
Specifies that this is a non-switched point-to-point asynchronous line. The line
description must be specified as a non-switched line when two systems are
directly connected with a NULL modem adapter.
Connection Dialog Scripts:
To control whether AS/400 uses a connection script,
you configure the Use connection dialog script field on the point-to-point
configuration profile. Valid values for this field are:
N No login sequence is required beyond the physical modem connection.
Y A connection dialog script is required. Each connection script contains a
text template that outlines the exchange of authorization and connection
parameters with a remote host.
Security:
For information about security for AS/400 support of the SLIP protocol,
see the
Tips and Tools for Securing Your AS/400
book.
PPP/SLIP over *PPP
You must use the Operations Navigator to configure and administer PPP and
SLIP profiles using a *PPP linetype.
If you use the command line interface to control Dial-in and Dial-out operations,
you can still use these functions:
v STRTCPPTP to START *PPP profiles
v ENDTCPPTP to END *PPP profiles
v WRKTCPPTP to Work with *PPP profiles, but only in a limited capacity:
v 9 (Start)
v 10 (End)
v 12 (Work with line status)
v 14 (Work with session job)
