Modem 34336

The Character Length option is available for all modes (asynchronous

operation only). It selects a character length of 8, 9, 10, or 11 bits for

character asynchronous operation. The same character length must be

selected for both the local and the remote modems. Use pushbuttons

1 and 3 to select the desired character length.

• 8 BITS: 1 start bit, 6 data bits and 1 or more stop bits.

• 9 BITS: 1 start bit, 7 data bits and 1 or more stop bits.

• 10 BITS: 1 start bit, 8 data bits, including parity, and 1 or more stop bits.

• 11 BITS: 1 start bit, 9 data bits, including parity, and 1 or more stop bits.

In Hayes mode, character length is set automatically under most conditions.

The Parity option is available for all modes. Parity selections are effective

only if error correction or buffer mode has been enabled or if the Modem

is in 2-Wire Dial (Hayes) mode. For most applications, parity should be set

to NONE.

The following parity options are available: NONE (no parity), ODD, EVEN,

MARK (parity is always 1) and SPACE (parity is always 0). All parity settings

except NONE automatically enable parity conversion (except in Hayes

mode), meaning that the parity of received data is converted to match the

selected parity option.

In Hayes mode, parity is set automatically under most conditions.
