In C #, how do you communicate through Kermit through the serial port?

I am going to start in a project where I need to contact (extract data) from a medical device via a serial port. The documentation for the device says that it communicates using the Kermit protocol. Ten years have passed since I even thought about Kermit. 20 years since I used it. Are there any libraries for this? If I give up on myself, what is connected with it?

I am developing in .NET 4.0 C #.
