One of the advantages of locking a serial port at 115,200 bps, rather than 57,600 bps, is reduced latency. For those that might be interested, here is a measurement of the latency effect of the DTE rate. Solid, nearly error-free 28,800 connections were possible, but to be safe the modem speed was locked down to 26,400 bps. Prior tests established that the POP was locked at 115,200 bps. 90 pings were performed at both 57,600 and 115,200 bps using Microsoft's ping applet, which has millisecond timing resolution.
