Oh yeah! A new version of the Citrix Virtual Desktop Agent version 3.1.3236 has been released.
Thanks Mr. Shawn Bass for picking this up =)

Here is a list of fixes in this release:

Redirected COM ports cannot be accessed outside of a user’s logon session. This enhancement allows you to issue a “net use com4: \\client\com1” command to add a global device link named “COM4” to the redirected COM1 port, allowing processes outside of the user’s logon session to access the COM port. To enable this enhancement, you must set the following registry key:

HKEY_LOCAL_MACHINE\Software\Citrix\PortICA\Serial
Name: CreateGlobalDevice
Type: REG_DWORD
Data: <greater than zero>

[From XDE310VDA002][#206151]

After reconnecting to a disconnected session, mapped COM ports might no longer be available.
