This chapter describes the function and displays the syntax of TN3270 commands. See the Access Services Command Reference publication for more information about defaults and usage guidelines.
keymap keymap-name keymap-entry
no keymap keymap-name
To define specific characteristics of keyboard mappings, use the keymap global configuration command. To remove the named keymap from the current image of the configuration file, use the no form of this command.
| keymap-name | Name of the file containing the keyboard mappings. The name can be up to 32 characters long and must be unique. |
| keymap-entry | Commands that define the keymap. |
keymap-type keymap-name
no keymap-type
To specify the keyboard map for a terminal connected to the line, use the keymap-type line configuration command. To reset the keyboard type for the line to the default, use the no form of this command.
| keymap-name | Name of a keymap defined within the configuration file of the access server or router. The TN3270 terminal-type negotiations use the specified keymap type when setting up a connection with the remote host. |
show keymap [keymap-name | all]
Use the show keymap EXEC command to test for the availability of a keymap after a connection on a access server or router takes place.
| keymap-name | (Optional) Name of the keymap. |
| all | (Optional) Lists the names of all defined keymaps. The name of the default keymap is not listed. |
To determine ASCII-hexadecimal character mappings, use the show tn3270 ascii-hexval EXEC command.
show tn3270 character-map {all | ebcdic-in-hex}
To display character mappings between ASCII and EBCDIC, use the show tn3270 character-map EXEC command.
| all | Displays all nonstandard character mappings. |
| ebcdic-in-hex | Displays the ASCII mapping for a specific EBCDIC character. |
show ttycap [ttycap-name | all]
To test for the availability of a ttycap after a connection on an access server or router takes place, use the show ttycap EXEC command.
| ttycap-name | (Optional) Name of a ttycap. |
| all | (Optional) Lists the names of all defined ttycaps. The name of the default ttycap is not listed. |
terminal-type terminal-name
no terminal-type
To specify the type of terminal connected to the line, use the terminal-type line configuration command. To reset the terminal type for the line to the default, use the no form of this command.
| terminal-name | Name of a termcap defined within the configuration file. The default is VT100. |
To configure the Cisco IOS software to use the mask set by the data-character-bits line configuration command or the terminal data-character bits EXEC command, use the tn3270 8bit display line configuration command. To restore the default 7-bit mask used for TN3270 connections, use the no form of this command.
[no] tn3270 8bit transparent-mode
To configure the Cisco IOS software to use the mask set by the data-character-bits line configuration command or the terminal data-character bits EXEC command, use the tn3270 8bit display line configuration command. To restore the default 7-bit mask used for TN3270 connections, use the no form of this command.
tn3270 character-map ebcdic-in-hex ascii-in-hex
no tn3270 character-map {all | ebcdic- in-hex} [ascii-in-hex]
To create a two-way binding between EBCDIC and ASCII characters, use the tn3270 character-map global configuration command. To restore default character mappings, use the no form of this command.
| ebcdic-in-hex | Hexadecimal value of an EBCDIC character. |
| ascii-in-hex | Hexadecimal value of an ASCII character. |
| all | Indicates all character mappings. |
tn3270 datastream [extended | normal]
no tn3270 datastream
To enable the TN3270 extended datastream, use the tn3270 datastream extended global configuration command. Use the no form of the command to return to the normal TN3270 datastream.
| extended | Extended datastream. |
| normal | Normal datastream. This is the default. |
[no] tn3270 null-processing [3270 | 7171]
To specify how NULLs are handled, use the tn3270 null-processing global configuration command. Use the no form of the command to return to 7171 NULL processing.
| 3270 | NULLs are compressed out of the string, as on a 3278-x terminal. |
| 7171 | NULLs are converted to spaces, as on a 7171 controller. 7171 NULL processing is the default. |
To lock a terminal after input error until the user resets the terminal, use the tn3270 reset-required global configuration command. Use the no form of the command to return to the default of no reset required.
ttycap ttycap-name termcap-entry
no ttycap ttycap-name
To define characteristics of a terminal emulation file, use the ttycap global configuration command. To delete any named ttycap entry from the configuration file, use the no form of this command.
| ttycap-name | Name of a file. It can be up to 32 characters long and must be unique. |
| termcap-entry | Commands that define the tttycap. Consists of two parts (see this command in the Access Services Command Reference for details). |
