#MAP COM PORT CITRIX POLICY DRIVER#
The initial CDM driver was based on the NT file redirector and it was time to move the technology forward. Secondly, the Client Drive Mapping has been completely redone for PortICA using the OSR FSDK toolkit. First, splitting it up hopefully will make it easier to support when one device has trouble. Instead of just having one monolithic driver for CDM (Client Device Mapping), PortICA will have four drivers. I’ll give you some some technical detail of how things are going to work in PortICA.
#MAP COM PORT CITRIX POLICY HOW TO#
I have often mentioned this during PortICA to the test people and others and it is very relevant to understanding how to select the right technique.

It is really just a tag to tell the provider and driver that it needs to treat the COM port as being more advanced. What is the alternative?ĬLIENTPORT makes all the difference. So, this mapping is good for basic printing but not good for something that is more aware. Things like HyperTerminal simply will not work. If you map to your COM port this way, you will not be able to take advantage of the applications that can access the more recent COM Port API (which translates to the COM Port API that were first included in Windows 95). Where’s the the basic assumption goes wrong.
#MAP COM PORT CITRIX POLICY CODE#
The protocol for the old COM port code is fairly basic and is very similar to the old LPT port mapping code (which is limited to LPT1 and LPT2). It, in turn, asks for access to the device from CDM.SYS which also concludes that we are dealing with the old way. This invokes code in our CDM provider that parses the path and realizes that we are dealing with the old way. If you do the most natural thing, you are going to end up mapping devices using the OLD way of doing COM ports. The mapping is where you decide what kind of COM port mapping code you are going to use. This is the whole reason I decided to write this post. I recently noticed that CPS has a policy to automatically map the COM ports but this is a very recent development (as far as I know it is new to 4.5). One of the key steps to getting this working is to enable COM port mapping in the policies and to map the COM ports in the logon script. With this level of support, things like HyperTerminal work with remote COM ports.
#MAP COM PORT CITRIX POLICY SERIAL#
The applications will think they are dealing with a normal local serial port when really it is doing work with the client’s serial port (note I’m going to use COM and serial port interchangeably even though Microsoft defines them differently). This means that it covers a much broader range of applications. Instead of just acting like a basic DOS device, it actually supports all the IOCTLs like a normal serial driver. It supports (hypothetically) all the client COM ports and does so in a much more native fashion. The new way does much more work to make the COM port remote.

Perhaps Citrix was worried that merging the old and new way would potentially break the customers depending on the old way. Believe it or not, customers out there are still using it this way. In the early days it was common to have these ports defined for Point of Sale (POS) to control a cash register drawer or print receipts. This was initially enabled to allow printing to simple printers on COM1 and COM2. The old way is very basic and is focused primarily as treating the COM port like a file destination for the sake of printing. It is similar to how there are multiple layers of supporting things related to printing. Don’t ask me why the two ways weren’t combined. Why two? Well, one is the old way of doing things and the other the newer. There are two kinds of COM port mapping support in Citrix. Unfortunately things are never as easy as they sound. The concept is that it is possible to use COM ports on the client from server applications. COM Port Mapping is perhaps more the back water of the more traditional features. Some features in Citrix Presentation Server are mostly unknown to large groups of people.
