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.

Escape Pass Codes

Command	Description
+ + ESC ESC	Exit Pass Mode:
	Typing a plus (shift =) followed by another plus followed by an ESC (the escape
	key) followed by another escape exits the pass mode. The Telnet session
	returns to "normal".
+ + ESC A	ASCII Display Mode:
	Typing a plus (shift =) followed by another plus followed by an ESC (the escape
	key) followed by an 'A' sets the display to ASCII mode. Any ASCII characters
	received by the device will be displayed by their ASCII symbol. Any non-ASCII
	characters will be displayed with a \ followed by two hex characters to indicate
	the characters hex value.
+ + ESC D	Decimal Display Mode:
	Typing a plus (shift =) followed by another plus followed by an ESC (the escape
	key) followed by a 'D' sets the display to decimal mode. Any characters
	received by the device will be displayed with a \ followed by numeric characters
	to indicate the characters decimal value.
+ + ESC H	Hex Display Mode:
	Typing a plus (shift =) followed by another plus followed by an ESC (the escape
	key) followed by an 'H' sets the display to hexadecimal mode. Any characters
	received by the device will be displayed with a \ followed by two hex characters
	to indicate the characters hex value.

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.

WindowsTM 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.

Linux Telnet client

The Linux Telnet client has three anomalies that are known at this time: A null (\00) character is sent after a carriage return.

If an ALT 255 is entered, two 255 characters are sent (per the Telnet RAFT).

If the code to go back to command mode is entered (ALT 29 which is ^]), the character is not sent, but Telnet command mode is entered.
