a) in the configuration file:

180 3420 tape01.aws maxsizeM=16 eotmargin=131072 compress=0

b) via devinit panel command:

devinit 180 tape02.het compress=1 maxsizeM=32 eotmargin=65536

devinit 180 tape03.het eotmargin=131072 compress=1 maxsize=0

Example 2:

Resolution of the arguments using ‘*’ lines.

The following ACF file

* compress=0

tape01.aws

* compress=1

tape02.aws

is equivalent to this one

* compress=1

tape01.aws

tape02.aws

6.9 Channel-to-Channel Adapters

6.9.1 Introduction

The Channel-to-Channel Adapter device statements define CTC adapters to the Hercules configuration.
All of the communications emulation implemented within Hercules use a CTCA (Channel-to-Channel
Adapter) type device. Depending on the type, the CTCA device will provide either a point-to-point or a
virtual network adapter interface to the driving system's TCP/IP stack or in the case of CTCT, a true
CTCA connection to another instance of Hercules via a TCP/IP connection.

All current emulations, with the exception of VMNET and CTCT use the Universal TUN/TAP driver on
Linux and TunTap32 (WinPCap) on the Windows platforms which creates a network interface on the
driving system which allow Hercules to present frames to, and receive frames from the TCP/IP stack. This
network interface is configured on Linux platforms by the ‘hercifc’ program which is invoked by Hercules
after the TUN/TAP device is opened.

The following are the emulation types currently supported:

6.9.2 CTCI (Channel-to-Channel link to TCP/IP stack)

6.9.2.1 Function

The CTCI is a point-to-point connection with the TCP/IP stack of the driving system on which Hercules is
running.
