Hello Jakub,
You connect to the Moxa via TCP/IP, then you don't have to make these settings:

> asynSetOption("LAKE1", -1, "baud", "9600")
> asynSetOption("LAKE1", -1, "bits", "8")
> asynSetOption("LAKE1", -1, "parity", "odd")
> asynSetOption("LAKE1", -1, "stop", "1")

You have already done this on the Moxa.

Which mode (socket?, reverse terminal?) have you set on the Moxa for the port to which the lakeshore is connected to?
Gruss Heinz

I configured the serial connection on the moxa, asyn, and the device to 9600 baud, 8 data bits, and one stop bit, and I can see that I am communicating with the device on some level, however, the responses I am seeing don't seem correct; they are full for unexpected characters, and don't match the format listed in the manual. I am guessing there is still something I missed in the configuration of the serial connection.
