Doesn't sound like that fast an interrupt. The 16550 has a 16-byte send and receive fifo. Set the rx interrupt @ 14, and the tx @ 2. 230400/8 = 28800 chars /s 28800 / 14 = 2057 interrupts / s. This should be well within reach of a pentium-class machine. To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
