When I was using the autobaud setting (s51=255||254||253), I did have
trouble with 38,400. I didn't investigate because I wanted to 57,600. I
now lock DTE at 57,600, and I have not had any problems. (I use uAccess
and a DigiCHANNEL Nu/4i on a Macintosh Quadra 700.) (I assume you have
verified that your machine's hardware can support a clean and sustained
38400 since many machines stop at 19200.)
