Thank you Eric,
I thought of doing it as you suggest.  I thought it useful to ask before committing myself, since my knowledge of asyn is only sketchy.

Could you not just have 32 ports?

drvAsynIPPortConfigure("L01","192.168.1.1:1255 UDP",0,0,0)
drvAsynIPPortConfigure("L02","192.168.1.2:1255 UDP",0,0,0)
drvAsynIPPortConfigure("L03","192.168.1.3:1255 UDP",0,0,0)
