I have a problem with Client COM port mapping with PS 4.5....
NET USE COM1: \CLIENT\CLIENTPORT:COM1 returns an error 55, the resource is no longer available.
NET USE COM1: \\CLIENT\COM1: returns a succes but portmon shows now traffic flow... and the application fails.
Am I missing something?
BTW it is a medical device connect via a local COM port that needs that the .net application talks to but fails to even see an active COM port.
I have disabled local COM ports on the Citrix server just incase the were interfering in some way.
I have also checked the ICA protocol settings to make sure COM ports havent been disabled.
Any help would be appreciated.

Somtimes I have found that COM1 port will not work and I will use com2.
net use com2 \\client\com2:
Brett, I would enable the com ports on your servers and also make sure com ports are enabled in the presentation server console policy.
Tony had a valid point as well with trying com2

Thanks for your advise, what I have discovered is that that NET USE COM1: \CLIENT\CLIENTPORT: is no longer required as NET USE COM1: \CLIENT\COM1: does the same.
The problem turned out to be the the c# com port class with mapped Client ports.
It fails when trying to query the baud rate.
