Console Redirection
If there is no video device detected during boot up, BIOS keyboard and screen I/O can be
redirected to the COM2 RS-232 serial port. CMOS configuration can be modified over this
redirected console. ANSI or VT102 terminal emulation is recommended.
When console redirection is enabled, press CTRL-C on the terminal emulator to enter CMOS
Setup; the BIOS ignores DEL from a PS/2 keyboard. This is normal operation of the Lynx.
COM2 is configured for standard serial port communication:
• 9600 Baud
• Parity: None
• Flow Control: None
• Data Bits: 8
• Stop Bits: 1
Console redirection remains active when POST completes and the operating system boots. Text-
based operating systems such as DOS and Linux can be controlled over this connection.
To enable console redirection, there must be no video device detected, the console redirection
option in Custom Configuration must be set to Auto, and there must be a terminal (such as
Windows HyperTerm) detected at COM2.
