I just finished one of these.   I wrote an asynOctet interpose layer that I push on the IP port driver.    Then I use StreamDevice %r conversion.

Ordinarily for such tasks I would use streamDevice, but the command protocol for this device (a CPI RF amplifier) is all binary, not strings, and even includes the requirement to byte stuff when framing characters are in the packet payload, as well as compute checksums on the packets.
