! 9600 baud
! No parity
! 8 bits
! One stop bit
To use an ASCII terminal as the console device for your system, set the serial baud rate, parity,
data length, and stop bits of the terminal to match the serial console settings. For proper display of
Setup and POST messages from the BIOS, you must use an IEEE-compatible terminal or terminal
emulation program that implements the standard ASCII cursor commands. The required
commands and their hexadecimal codes are listed in Table 2-14.
Some Programs that emulate an ASCII terminal do not properly support the basic ASCII command
functions shown in Table 2-14. Ampro provides a suitable PC terminal emulator program,
TVTERM, on the Common Utilities diskette.
After booting this system, the keyboard and screen of the serial terminal become the system
console.
Note
The programs you execute via the serial terminal must use ROM
BIOS video functions (rather than direct screen addressing) for the
display I/O. Some programs that emulate an ASCII terminal do not
properly support the basic ASCII command functions shown in Table
2-14. Ampro provides a suitable PC terminal emulator program,
TVTERM, on the Common Utilities diskette.
After booting this system, the keyboard and screen of the serial terminal become the system
console. The programs you execute via the serial terminal must use ROM BIOS video functions
(rather than direct screen addressing) for the display I/O.
Note
DOS programs that write directly to video RAM will not display
properly on a serial console device.
