Well, I *think* so. How can I tell? I use setserial with spd_cust and a divisor of 1 with the card jumpered to a base of 3.6864 Mhz; this is supposed to produce 230.4K. Before doing that, using spd_vhi giving 115000 bps I tell the Bitsurf the speed is now 230400. I then switch speeds and the bitsrfr responds. It no longer talks to me if I talk to it at 115000. In fact, it often resets when I do. -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] . Trouble? e-mail to [EMAIL PROTECTED] .
