There are two levels at which asyn can be used with the motor record. The first is as the low-level communication layer between the motor driver and the serial, Ethernet or GPIB port. That use is supported by any motor controller supported by the motor module, including many models from Newport, IMS, ACS, Faulhaber, and many others. With that asyn layer, you can use either local serial ports or Ethernet to serial converters with no changes to the motor driver.
The second use is what Peter described, i.e. as the interface between the motor record device support and the motor record driver. That is a relatively recent development, and is currently supported for the Newport MM400, Newport XPS, and Delta Tau TPMAC.

It would help if you gave a few more details about the exact model of motor.
The latest release of the motor support (R6-1, from http://www.aps.anl.gov/upd/people/sluiter/epics/motor/R6-1/motorR6-1.tar.gz) includes a driver for Newport motor controllers, using Asyn as the low-level protocol to talk to the motor controller. There is also a driver for Delta-Tau motor controllers (tpmac at http://epics.svn.sourceforge.net/epics/applications/tags/tpmac/3-3/) which also uses this release of motor support, and serial Asyn as the lowest layer transport to the motor controller.
To support your motor, you could have a look at one of these, and adapt it to talk the protocol required by your serial-port motor. The ethernet/serial converter box should be transparently supported by Asyn, if you're lucky.

Subject: EPICS Driver for motor through Ethernet/Serial?
hi,
I want to find a EPCIS 314 driver for a motor which has a serial port, connected to an Ethernet/Serial converter boxes, IOC is redhat linux. all the control string is ASCII code. Is there somebody using Asyn driver to implement this? Can you send me an application?
Thanks a lot for your help.
Best wishes
