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.

My st.cmd file includes following lines:

  asynSetOption ("serial",0,"bits","8")

  asynSetOption ("serial",0,"parity","none")

  asynSetOption ("serial",0,"stop","1")

  asynSetTraceMask("serial",-1,0x9)

  asynSetTraceIOMask("serial",-1,0x2)
