LinuxQuestions.org - [SOLVED] Using serial port from Linux guest on VMware

Hello,
I would like to send data to the virtual serial port provided by Vmware. Actually, my laptop is not equipped with a physical serial port, that's not a problem since I use the file option available in VmWare (Setting->Add->Serial Port -> Use output file)
The file is in the same root folder of my virtual machine and has been created by VmWare after the first configuration of the serial port.
I also checked the vmaware BIOS which has the AUTO option for the serial port, thus it should detect the serial port automatically.
When I perform a redirection on the serial port something like

Code:

echo "hello" > /dev/ttyS0

I receive no errors, but if I read from the serial port

Code:

cat /dev/ttyS0

the command gets stuck and the file used from Vmware
to log the data to the serial port is empty.

I also tried to use the command

Code:

setserial -g /dev/ttyS0

before starting to write with the echo command
setserial prompts the message:

Code:

/dev/ttyS0, UART:16550A, Port: 0x03f8, IRQ: 4

(apparently correct).

my system configuration is:
VmWare 7.1.13 running on Windows 7 (host system)
Linux 2.6.24 (guest)
Any help?
