Hi,

I have a windows XP computer running on an ESXi 5 Server.
We need to plug a serial device to our ESXi server physical port and connect the port to our Windows XP computer.

I already connected the serial cable and added the port to the XP computer, but I'm not able to transmit/receive over the serial connection (I attached a picture of the configuration

Could I have the steps I need to follow?

Thank you,

have you enabled Serial Ports in the Virtual Machine BIOS and added serial port devices to the VM?

please upload screenshots, USB to Serial Port Adaptors, work much better than standard serial devices.

USB devices can then be added to the VM, see my EE Article

I changed the BIOS settings for the serial ports from Auto to Enabled, but I'm still not able to setup a connection. the Device manager shows COM1 and COM2 by default on all my other virtual machines located on the same EXSi server.

I have a serial device connected to an HP Proliant DL385 G7, that 'passes through' to an XP VM as well. It's a 'security' device. It's a bit "quirky" sometimes to get it to work. Edit the VM settings, select the Serial Port 1 you added, choose 'physical serial port' as your connection and from the drop-down choose "/dev/char/serial/usart0" and make sure the Device Status (at the top) has both 'Connected' and 'Connect at Power On' selected. If you don't have the right "Connection" selected, I believe the 'Connected' option will uncheck itself as it can't "see" the device you connected to the Host. At least, that's the issue I experienced.

Please take a look at the images. The host server does have two serial ports

Ok, did the config work I suggested? If not, try to use the "usart1" device from the drop-down to see if it 'connects'.

Thank you for all your help.

I had an extra USB-Serial cable, and I was able to set up the serial by following your steps.
