Kevin - 

Thank you for your response. 

1. There are no errors that I can see after the call to drvsynSerialPortConfigure. I can use the asyn port to communicate with the card and get the expecterd response via caput and caget.
2. I do receive the following motor record error once I try creating the motor record.
1. recGblRecordError: motor_init_record_com(): card does not exist! Illegal field value PV: serial:m1
   
   

    I'm using the following line in st.cmd to load the motor record:

    dbLoadTemplate("motor.substitutions")

    and motor.substitutions contains:

    file "/opt/epics/support/motor/db/motor.db"

    {

    Appreciate any input that you may have.

Jim,

The OmsPC68 support in the motorOms module is model-1 driver which uses motor.db.  VME_IO is correct for the controller:

https://nam12.safelinks.protection.outlook.com/?url="">

Newer model-3 drivers generic asyn motor device support which works with asyn_motor.db. 

I have a couple questions:

1. Are there any errors after the call to drvAsynSerialPortConfigure?

2. Are there any motor record errors at iocInit?
