PAD Profile Table Record

#20, Echo Mask

Range:

0 to 255

 

 

Default:

1+2+4+8+16+32+64+128

 

 

Description:

Specifies the echo mask (which characters are not echoed):

 

 

 

• 0: No echo mask (all characters echoed).

 

 

 

• 1: No echo of <CR>.

 

 

 

• 2: No echo of line feed <LF>.

 

 

 

• 4: No echo of <VT>, <HT>, or <FF>.

 

 

 

• 8: No echo of <BEL> or <BS>.

 

 

 

• 16: No echo of <ESC> or <ENQ>.

 

 

 

• 32: No echo of <ACK>, <NAK>, <STX>, <SOH>, <EOT>,

 

 

 

<ETB>, or <ETX>.

 

 

 

• 64: No echo of editing characters as designated by parameters

 

 

 

#16, #17, and #18.

 

 

 

• 128: No echo of all characters in columns 0 and 1 of the

 

 

 

ASCII table not mentioned above, and <DEL>.

 

 

 

Note

 

 

 

 

 

 

 

 

Combine several parameter values by summing:

 

 

Example: 3 = 2 (no echo of line feed) + 1 (No echo of <CR>).

 

 

If parameter #2 Echo = 0 (disabled), parameter #20 Echo Mask is

 

 

ignored.

 

 

 

 

#21 Parity Treatment

Range:

0 to 7

 

 

Default:

7

 

 

Description:

Specifies how parity is treated on characters to and from the

 

 

attached device:

 

 

 

• 0: No parity checking or gen eration

 

 

 

• 1: Parity checked in received characters

 

 

 

• 2: Parity generated in transmitted characters

 

 

 

• 4: Parity stripped from received characters

 

 

 

Note

 

 

 

 

 

 

 

 

Combine several parameter values by summing:

 

 

 

– Example: 3 = 2 (parity generated in transmitted character) +

 

 

 

1 (parity checked on received characters)
