Example 2:

Define PTP (MPCPTP ESCON CTC link) adapters on device addresses 0440 and 0441. The name of the
TUN/TAP special character device is “/dev/net/tun”. The IP address of the Hercules guest OS side is
192.168.1.99, the host network adapter to use is 192.168.1.100

0440.2 PTP -n /dev/net/tun 192.168.1.99 192.168.1.100

or

0440 PTP -n /dev/net/tun 192.168.1.99 192.168.1.100
0441 PTP -n /dev/net/tun 192.168.1.99 192.168.1.100

Example 3:

Define PTP (MPCPTP ESCON CTC link) adapters on device addresses 0E20 and 0E21. The WinPcap
device driver capture buffer has to be set to 2048 KB and the TunTap32 I/O buffer size has to be set to
256 KB. The IP address of the guest operating system running under Hercules is 192.168.1.99 and the
MAC address of the network adapter to use is 00-80-B3-E1-DF-69.

0E20.2 3088 PTP -n 00-80-B3-E1-DF-69 -k 2048 -i 256 192.168.1.99 0.0.0.0

or

0E20 3088 PTP -n 00-80-B3-E1-DF-69 -k 2048 -i 256 192.168.1.99 0.0.0.0
0E21 3088 PTP -n 00-80-B3-E1-DF-69 -k 2048 -i 256 192.168.1.99 0.0.0.0

6.9.8 VMNET (Channel-to-Channel link via SLIP/VMNET)

6.9.8.1 Function

If the emulation mode is not specified on the configuration statement, it is assumed to be a point-to-point
link to the driving system's TCP/IP stack using Willem Konynenberg's VMNET package. This provides the
same function as the CTCI mode of operation, except that it uses a virtual SLIP interface instead of the
TUN/TAP driver.

6.10 FBA DASD De
vices

6.10.1 Function

This device statement is used to define a FBA DASD device to the Hercules configuration. The argument
specifies the name of a file which contains the FBA DASD image or the INET address of a Hercules
shared device server.

The file consists of fixed length 512-byte records each of which represents one physical block of the emu-
lated disk. To allow access to a minidisk within a full-pack FBA DASD image file two additional arguments
(origin and numblks) may be specified after the filename.
