Console Redirection
NCR S46 Server MP-RAS Support Guide 2-9
Note: When you change the console redirection baud rate, you must
synchronize your modem’s baud rate to the new speed. To do this, select
“Enable Auto Answer” or “Disable Auto Answer” from the “Modem Utilities”
menu of the Diagnostic Partition or Platform CD-ROM.
How Redirection Works
During console redirection, the remote terminal (a system with a modem
running a package such as PROCOMM PLUS) sends keystrokes to the local
server, which then passes back video information.
Information from the local server’s video buffer is sent to the remote terminal
for display. Keyboard information from the remote terminal is forwarded to
the local server’s application using the INT 16h BIOS Keyboard Services
interrupt.
Keyboard Input
Keyboard strings are based on the ANSI BBS terminal standard. Since these
terminals do not support all of the keys on the standard 101-key U.S.
keyboard, some combinations of keyboard characters are defined to represent
keys such as the following:
•
F5 through F12
•
Alt+A through Alt+Z
•
Alt+0 through Alt+9
•
Page Up and Page Down
The server application must interpret these non-standard character
combinations correctly.
Keyboard strings are fully defined in the “Key Mapping for Non-ASCII Keys”
section later in this chapter.
