I am trying to connect to a device connected to the serial port of my ESX server.  The question is - what command that comes natively with ESX 4.0 server will let you communicate with the serial port?  I know the device name /dev/ttyS0.  Thanks.

Typically you would connect the serial port to a Virtual Machine and not to ESX. I just looked a a client setup and that is broadly how it works (same as VMware Workstation). Except the new physical server in question has not serial port, so I cannot test.

Have you tried editing the settings of your Virtual Machine and adding it there?

If your server has on board serial port such as Dell R710, you can emulate the serial port just by assigning a serial port in VM config
From there, the VM will treat it as a normal physical serial port, as you can see in my photo below, there is a serial cable connected to the esx host
If there is no onboard serial port, you can get a PCI based serial port but always check vmware HCL before buying anything
