T10 Serial Redirection to RDP Issues

T10 Serial Redirection to RDP Issues

Hi guys. I’m having issues redirecting serial ports for use in a PURE RDP environment.

The thin client recognizes that the usb to serial cable is connect to port 3 and assigns it to COM3. (I don’t know why COM3 and not COM1 or COM2 this is the only serial to usb cable to ever be plugged into this device but I’m getting off track…)

running change port /QUERY from a command prompt in the RDP session shows the ports as being redirected

C:Usersfakeuser>change port /query

AUX = DosDevicesCOM1

COM1 = DeviceRdpDrPort;COM1:8tsclientCOM1

COM2 = DeviceRdpDrPort;COM2:8tsclientCOM2

COM3 = DeviceRdpDrPort;COM3:8tsclientCOM3

COM4 = DeviceRdpDrPort;COM4:8tsclientCOM4

NONSPOOLED_COM1 = DeviceSerial0

NONSPOOLED_COM2 = DeviceSerial1

however nothing I do (printing to COM3 from software/testing with generic/txt printer to COM3/echo “testing<1B>E” > COM3/etc) will make anything print to the device. can anyone offer me any insight as to what the issue could be here?

I know the adapter and printer/cables are good as the device works as expected if I don’t forcelocal the usb device and allow the adapter to show up as a new COM port on the RDP server but this is not desirable because this is a load balanced environment AND the software we are using only supports using COM1-COM9 (hint: we have more than 9 workstations) so just to clarify I need COM redirection not to get the serial to usb adapter to show up in the RDP session.

thank you in advance to anyone that can offer any advice as to what the issue could be.
