You might want to add

asynSetOption("serial", 0, "crtscts", "N")

to ensure that you're not attempting to use RTS/CTS hardware handshaking.

Do you have any type of serial line analyzer to check that the wiring is set up properly?  Even a simple little device with indicator LEDs can be very useful.

Also, try just jumpering pins 2 and 3 on the PC serial port connector.   Then confirm that you see the '*IDN?', and whatever terminators you're using echoed back.
