Especially since minimum theoretical time should be on the order of 88ms
for uncompressed data (64 bytes for ping / 1.4kB/sec slip line * 2).

On the 28.8 V.FC modems I am using now (which say they're only doing 26.4)
the smallest ping time I get is 115 ms.  It tends to hover around 120-140ms.
This is with v.42bis turned on, and MNP 10.  Oh, I have my DTE speed set at
