I find that 120 - 180 ms is normal for modems.
If a customer wants to reduce that, I would suggest that they disable
software compression in dial-up network properties as well as data
compression in their modem settings. Its a good idea to leave error
correction on. The point here is to reduce any sources of latency
originating from the various compression schemes in use that overlap in many
cases.
They should be able to drop to 80 ms but of course will get slower transfers
of compressible data. I'm not sure if you are able to get around the STAC
card though.
