http://perforce.freebsd.org/chv.cgi?CH=30415 Change 30415 by marcel@marcel_nfs on 2003/05/02 15:33:02 Update documentation: COM_FORCECONSOLE is gone. Use boot -h or set boot_serial=YES. COM_LLCONSOLE is gone. Remote GDB support is going to be handled like the console support, which makes this flag obsolete. COM_ESP is gone. This driver is for UARTs. Enhanced serial ports are better off with their own driver. The ESP support was limited to UART compatibility only anyway. COM_MULTIPORT is gone. Multiport cards are going to be handled by puc(4). This needs more work of course. COM_ST6650* is gone. We'll detect at runtime (now only FIFO size, but based on that we can also probe other features). Document hint.sio.0.baud as a way to set the default baudrate. This makes compile-time defaults mostly redundant. Both CONSPEED and GDBSPEED have been retained for now.
