4.2.1Special Parameters for X.25 PU's

The following parameters may be either entered here, or included in the Open/Call/Answer
commands (depending on the Virtual circuit type chosen) entered form the
SYSTEM_REQUEST command entry line from the terminal initiating communication with
the host.
Packet Size
Virtual Circuit Type
The number of bytes allowed in the data field of the
packet.
For SVCs, this parameter configures the maximum size
of call packets accepted by the controller - it sets the
limit on variable packet sizes.
For PVCs, the packet size value is not negotiable and
remains constant at the value selected.
0 = 64-byte packet
1 = 128-byte packet
2 = 256-byte packet
3 = 512-byte packet
This is the type of connection:
[1] = PVC only. Permanent Virtual Circuit; emulates
"End to End" connection.
[2] = SVC Ans. Incoming calls only; choose this option
ONLY if you do not intend to place any calls to the Host.
[3] = SVC Calls. Outgoing calls only. Choose this
option only if you do not intend to receive incoming calls
from the host system.
