17.17 Accessing Serial Devices
Prev	Chapter 17 Windows Connector	Next

The Windows connector provides serial device mapping, which enables users to access external serial devices connected to a Sun Ray Client or an Oracle Virtual Desktop Client running on a Windows client computer. When initiating the Windows connecter, you need to configure the device mapping through the -r comport: option of the uttsc command.

Here is an example of mapping a serial device mounted on $UTDEVROOT/dev/term/a to the device name SER_A.

uttsc -r comport:SER_A=$UTDEVROOT/dev/term/a ip_addr

For details on how to determine where serial devices are mounted for a desktop client, see Section 15.4, “Accessing Serial Devices and USB Printers”.

Note

USB-to-serial adapters are not accessible through the generated device nodes. You must use USB redirection in a Windows session to access a serial device connected through a USB-to-serial adapter.

Once the serial device is mapped, there are various ways to verify that the serial device is available as mapped, such as SER_A in the previous example. See Table 17.11, “Windows Commands to Verify Available Serial Devices” for the list of some recommended commands and the notes that follow.

Table 17.11 Windows Commands to Verify Available Serial Devices

Windows Version	chgport /q	net use	mode	PuTTY
Windows XP	Yes, see notes	No	No	Yes
Windows Server 2003 R2	Yes	No	No	Yes
Windows 7, Windows 8, Windows Server 2008 R2, Windows Server 2012	Yes	No	Yes	Yes

Here are some notes for Table 17.11, “Windows Commands to Verify Available Serial Devices”.

chgport /q - This command is not part of Windows XP. However, you can copy both the change.exe and chgport.exe executable files from a Windows Server 2003 R2 system to a Windows XP system and use them. Under Windows XP, the chgport \q command will display the device if you map it using the following command, where COMn: is an unused COM port and mapped_name is the name of the mapped device:
```
net use \\COMn:\\tsclient\mapped_name
      
```
net use and mode - You should run both of these commands from the Windows command prompt.
PuTTY - This command is available free at http://www.chiark.greenend.org.uk/%7Esgtatham/putty/download.html. Do not type a colon (:) when entering a serial port in PuTTY, even if the mapped name contains a colon.
