Notes on Specific Telnet Clients
Telnet and terminal clients exhibit different behaviors in some situations. This section states some of the known
anomalies.
Windows 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.
Example
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 of the “255” characters are sent (per the Telnet RAFT).
If the code to return to Command mode is entered (Alt 29 which is ^]), the character is not sent, but the
Telnet Command Mode is entered.
