PC to HP 48G infrared communication

I know, that's why I said earlier "Sending ASCII data from the PC and receiving it via SRECV on the 48G works fine". I just wanted to test if anything is received and it was. Getting "kermit" in-between some binary data suggests that the data transmission is working, but that Kermit expects a response from the calculator (which is not possible because my IR connection works only in one direction).

edit: Maybe it is not even possible to do what I want. I thought Kermit supports unidirectional connections, but I might be wrong.
