D-Channel X.25

	Table 12-22: Character Delete

Value	Description

0 to 126	One decimal character from the ASCII Character Table is used as
	the delete character (refer to Appendix F). If parameter 16 is set to
	8, the character backspace (BS) can be used by the user to delete
	the last character stored in the PAD (i.e., the last character the PAD
	received from the local DTE).

127	Character DEL is used as the character delete character

default = ASCII decimal value 8 character BS

Note: Do not substitute a displayable ASCII character to initiate character delete. When used, a displayable character delete will delete both the initiating character and the object character. However, the monitor will continue to display the object character.

Parameter 17: Line Delete

Parameter 17 specifies the line delete character. When the PAD receives the line delete character from the local DTE device, the PAD deletes the entire last line of characters contained in the PAD buffer that were transmitted to the PAD by the local DTE device. If service signals can be transmitted by the PAD (parameter 6 is not set to 0), the PAD transmits a line delete service signal to the local DTE device. This deletes the entire last line of characters from the DTE device’s display. The format of the line delete service signal varies depending on the type of DTE device. Parameter 19 specifies the format of the line delete service signal for different DTE devices. Receipt of the line delete character is valid when the PAD is in the PAD data transfer mode and editing (parameter 15) is enabled, or the PAD is in the PAD command mode.

The function priority for duplicated characters (because of duplication of parameter assignments) follows the order of priority listed in the priority table provided for parameter 3.

Older DTE devices may not issue the character CAN (18H) for line delete as expected. Parameter 17 must be set according to the line delete character the DTE device is transmitting to the PAD.
