R2511-HP MSR Router Series Terminal Access Configuration Guide(V5)

85
Check whether the application mode is many-to-one, which may cause data for terminals to fall into
confusion. Upgrade to a router version supporting TTY one-to-one mode and switch to TTY one-to-one
application mode.
Pressing menu switching hotkey cannot bring up the menu
When a terminal is listing directories or outputting data, pressing the menu switching hotkey does not
bring up the menu. Perform VTY switching when the terminal is idle.
With terminal access enabled, a powered terminal is still down
• Check whether the asynchronous interface is configured with the undo modem command.
• Verify that the terminal cable is OK.
• Verify that the converter connecting the terminal and the router is wired correctly.
Only the first configuration file has a corresponding process when multiple configuration files are
configured
Check whether the listening ports configured in the configuration files are in conflict.
The terminal cannot display the login interface after configuration and no error message is logged on
the Unix server
Examine the configuration file to see whether the same application mode is configured on the router and
the Unix server. This problem occurs if the Unix server uses the many-to-one mode and the router uses TTY
one-to-one mode.
The terminal connected to a credit card (IC card) swipe reader does not work
View the hardware versions of the interface modules by using the display version command.
Confirm that the correct hardware versions of the interface modules are being used. 8AS modules have
two hardware versions: 1.x and 2.x. 8AS modules with a hardware version of 1.x do not support card
swiping. Those with a hardware version of 2.x support it. No such problems happen to any other
interface modules.
Some terminals cannot display the menu interface after power-on
Some terminals undergo a slow initialization process after power-on, so they may drop the menu
interface sent by the router and display a blank screen. Press the menu hotkey or any non-function key to
bring up the menu interface.
