Console Redirection - VersaLogic Copperhead VL-EBX-41 Reference Manual

C R
ONSOLE EDIRECTION
The Copperhead can be operated without using the on-board video output by redirecting the
console to a serial communications port. CMOS Setup and some operating systems such as DOS
can use this console for user interaction.
Console redirection settings are configured on the Serial Port Console Redirection submenu of
the Advanced tab. It is disabled by default. When enabled, the console will be available both at
the serial port and using the standard keyboard/video console. The video console may resize and
slow down to accommodate the slower serial console connection. By default, the serial console
uses 115200 baud, 8 data bits, 1 stop bit, no parity, and no flow control.
