Configuring X.25
Setting up X.25 PAD sessions
If you specify *F, the MAX inserts all the data into the user data portion of the call
packet (with a maximum length of 124 bytes), and the MAX flags the packet as a fast
select call.
• clr
The Clr command clears a virtual circuit by sending a Clear-Request packet (from a DTE)
or a Clear-Indication packet (from a DCE).
• facilities [ * | facilities ]
The Facilities command specifies which facilities to use in subsequent Call commands. If
you enter the Facilities command with no arguments, the MAX displays the current
facilities.
– If you specify an asterisk (*), the command clears the current facilities and resets
them to their default values. The default facilities are window size 2 and packet size
128 (420202430707).
– The facilities argument can consist of up to 63 hexadecimal digits. The MAX
converts the specified value you specify from hexadecimal format, and it becomes the
byte sequence inserted in the Facilities field of outgoing Call-Request packets.
• full
The Full command selects full-duplex mode.
• half [*] | [[-] <ch1>, <ch2>,...]
The Half command selects half-duplex mode and specifies the characters echoed. In
half-duplex mode, the MAX does not echo most characters. In half-duplex mode with
echo enabled, the PAD does most of the work of echoing and then discards the data
instead of sending it to the asynchronous device. The PAD can therefore provide line
folding, tab expansion, linefeed insertion, carriage return and linefeed padding, and
character and line deletion. For more information about these features, see “X.3
parameters and profiles” on page 6-14.
If you disable echo, the amount of processing the PAD must perform on every character
decreases substantially, and the PAD cannot perform line folding, tab expansion, or other
actions described in the previous paragraph. This mode is most efficient for file transfers.
The command’s arguments function as follows:
– If you specify an asterisk (*), the MAX does not echo any characters.
– If you specify only a list of characters (ch1, ch2, and so on), the MAX echoes only
these characters.
– You must specify each character in decimal format.
– If you insert a hyphen (-) before the list of characters, only the characters you specify
are not echoed.
– If you enter the Half command with no arguments, the command sets half-duplex
mode without altering the characters selected for echo by any previously entered Half
command.
• interrupt
The Interrupt command generates an Interrupt packet. An Interrupt packet can transmit
from 1 to 32 bytes of data to the remote DTE without being subject to flow control. The
exchange of Interrupt packets does not affect the exchange of data packets or flow-control
packets.
• listen [addr=<address> | data=data]
