Two things I found here:
--- "Hayes Optima 28.8k" "AT&F&C1&D3&K3&Q5E0Q1S0=1&W\r^OK"--- Hayes Optima 28.8k and Acura 14400 modem.AT&F&C1&D3&K3&Q5E0Q2s0=1&W
One recommendation uses Q1 instead of Q2 AT&F&C1&D3&K3&Q5E0Q1s0=1&W
Make sure you enter this with the DTE latched at the speed you want to use on the Hayes. &w locks the DTE speed to the current speed.
They have problems with lines with services like call forwarding; use bare lines instead.
We have a report that new (95/2/23) Acura 14400's have a problem with &D3, use &D2 instead.
