Use "spd_normal", and feed the real desired baud rate from your application. For instance, I used to use spd_vhi with ppp, and had 38400 in my ppp options. That resulted in 115200 comm port speed. With spd_normal, I put 115200 in my ppp options file, and I am back to getting consistent 33.6 connections on my ppp link.
My understanding is that the spd_hi and spd_vhi were a kludge for the old kernels and serial drivers that didn't understand speeds higher than 38400. They are no longer necessary in recent kernels.. my fix works with 2.0.32 as well, even though the spd_vhi stuff wasn't broken there.
