Security Gateway Manual XG-7100
Wrong Terminal Settings
Ensure the terminal program is configured for the correct speed. The default BIOS speed is 115200, and many
other modern operating systems use that speed as well.
Some older operating systems or custom configurations may use slower speeds such as 9600 or 38400.
Device OS Serial Console Settings
Ensure the operating system is configured for the proper console (e.g. ttyS1 in Linux). Consult the various
operating install guides on this site for further information.
PuTTY has issues with line drawing
PuTTY generally handles most cases OK but can have issues with line drawing characters on certain platforms.
These settings seem to work best (tested on Windows):
Window
Columns x Rows
80x24
Window > Appearance
Font
Courier New 10pt or Consolas 10pt
Window > Translation
Remote Character Set
Use font encoding or UTF-8
Handling of line drawing characters
Use font in both ANSI and OEM modes or Use Unicode line drawing code points
Window > Colours
Indicate bolded text by changing
The colour
Garbled Serial Output
If the serial output appears to be garbled, missing characters, binary, or random characters check the following items:
Flow Control
In some cases flow control can interfere with serial communication, causing dropped characters or other issues.
Disabling flow control in the client can potentially correct this problem.
On PuTTY and other GUI clients there is typically a per-session option to disable flow control. In PuTTY, the
Flow Control option is in the settings tree under Connection, then Serial.
To disable flow control in GNU Screen, add the -ixon and/or -ixoff parameters after the serial speed as in the
following example:
$ sudo screen <console port> 115200,-ixon
Terminal Speed
Ensure the terminal program is configured for the correct speed. (See No Serial Output)
Character Encoding
Ensure the terminal program is configured for the proper character encoding, such as UTF-8 or Latin-1, depend-
ing on the operating system. (See GNU Screen)
