My application requires a serial terminal connection from a laptop. Most laptops don't have a serial port so my idea is to emulate a serial port over a USB connection.
How does one add a USB serial port using the RL-ARM that terminates in the application - as opposed to just doing usb to serial conversion using usbd_vcom_usb2serial()?
I will be using Cortex-M3 LPC1768.
Thanks in advance.

Hi, thanks for that. Yes I had already implemented the equivalent of that available from NXP's CMSIS package (and it worked well). ics.nxp.com/.../lpc17xx.cmsis.driver.library.zip
What I was hoping to see was a RTX version using the Keil RL-ARM. There is no example of that.
The RL-ARM library only seems to have USB to serial conversion and nothing that goes from USB to an internal buffer (equivalent to adding another serial port to the processor - but over USB).
Any other thoughts besides just taking NXP's CMSIS v2.0 drivers and converting to use the RTX?
So can't you just add your buffer as you would for a serial port?
