To change the current definition, delete the definition displayed in the text box and type in the new one, either as the control key character equivalent or the decimal value of the ASCII character. For example, the default ASCII character RS can be entered by typing the character ^ twice, representing the keys Ctrl + ^ which, when pressed together would generate the RS code.

Decimal values are entered as three-digit numbers immediately preceded by an underscore character. Values with only two digits must be preceded by a zero. For example, the decimal value of RS is 30, so this would be entered as _030.

●Typeahead enabled Factory default: Unchecked

When TeemTalk is connected to an HP 3000, you normally have to wait for the host to send a prompt before you can enter new data at the keyboard, otherwise the data is ignored. Selecting this option will enable you to type continuously without waiting for the prompt. Data is stored in the keyboard buffer and each time TeemTalk receives a prompt it will send a line of data to the host. Block mode also supports typeahead.

●Host prompt character Factory default: ^Q (i.e. DC1)

Some hosts send a prompt character to the terminal to indicate that they are ready to receive the next line or block of data. This option enables you to specify the prompt character for your particular host. Most hosts either use the DC1 (^Q) character (e.g. HP 3000) or no prompt (^@) character.

When the Typeahead enabled option is checked, TeemTalk will wait for the specified prompt character from the host before transmitting the next line from the keyboard buffer.
