ESC Pass Codes
There are 'escape' codes in the pass mode. These codes can switch the display mode or exit pass
mode. The following 'escape' codes are defined.
Notes on Specific Telnet/Terminal Clients
Telnet and terminal clients will have different behaviors in some situations. This section states
some of the known anomalies.
Windows
TM
client programs
Anomalies occur when using a Windows client if you are not typing standard ASCII characters (i.e.
using the keypad and the ALT key to enter decimal codes). Most programs will allow you to enter
specific decimal codes by holding ALT and using keypad numbers.
For example, hold ALT, hit the keypad 1, then hit keypad 0, then release ALT. The standard line
feed code is entered (decimal 10). Windows will perform an ANSI to OEM conversion on some
codes entered this way because of the way Windows handles languages and code pages.
The following codes are known to be altered, but others may be affected depending on the
computer's setup.
Characters 15, 21, 22, and any characters above 127.
This affects both Windows Telnet and Terminal programs.
