5 If you selected Output to named pipe, configure the named pipe.
a (Windows host) Use the default pipe name, or type another pipe name.
The pipe name must begin with \\.\pipe\ and must be the same on both the server and the client.
For example: \\.\pipe\
namedpipe
b (Linux host) Type /tmp/socket or another UNIX socket name in the first text box.
The pipe name must be the same on both the server and the client.
c To send debugging information to an application on the host system, select This end is the server
from the first drop-down menu and select The other end is an application from the second drop-
down menu.
d To send debugging information to another virtual machine, select This end is the server from the
first drop-down menu and The other end is a virtual machine from the second drop-down menu.
6 To connect the port to the virtual machine when the virtual machine powers on, select Connect at power
on.
7 Click Finish to add the virtual serial port to the virtual machine.
8 (Optional) On the Hardware tab, select the new serial port, select Yield CPU on poll, and click OK.
This option is useful if you are using debugging tools that communicate over a serial connection. If the
serial port in the guest operating system is being used in polled mode rather than interrupt mode, you
might notice performance issues. This option forces the virtual machine to yield processor time if the only
task it is trying to do is poll the virtual serial port.
What to do next
If you set up a connection between two virtual machines, the first virtual machine is set up as the server. Repeat
this procedure for the second virtual machine, but set it up as the client by selecting This end is the client
when you configure the named pipe.
Change the Input Speed of a Serial Connection
You can increase the speed of a serial connection over a pipe to a virtual machine.
In principle, the output speed, which is the speed at which the virtual machine sends data through the virtual
serial port, is unlimited. In practice, the output speed depends on how fast the application at the other end of
the pipe reads inbound data.
Prerequisites
n
Use the guest operating system to configure the serial port for the highest setting supported by the
application that you are running in the virtual machine.
n
Power off the virtual machine and exit Player.
Procedure
1 In a text editor, add the following line to the virtual machine configuration (.vmx) file.
serial port_number .pipe.charTimePercent = " time "
port_number is the number of the serial port, starting from 0. The first serial port is serial0. time is a positive
integer that specifies the time taken to transmit a character, expressed as a percentage of the default speed
set for the serial port in the guest operating system. For example, a setting of 200 forces the port to take
twice as long for each character, or send data at half the default speed. A setting of 50 forces the port to
take only half as long for each character, or send data at twice the default speed.
