Setting Serial Port
After selecting Set Serial Port, you are prompted for the number of nulls.
Nulls are do nothing characters sent to the printer or other serial devices after
a carriage return. Slower terminals might require nulls because the carriage
takes some time to return to the first print column. Enter 0 or another value
and press [Return]. You are prompted for the carriage width of your printer.
Messages are automatically broken into lines that fit the page. You can
adjust the carriage width from 20 to 200 characters. Enter a value and press
[Return]. You are prompted for the baud rate.
Enter the baud rate in hundreds and press [Return]. The baud rate changes
the next time power is cycled or the DL20 is reset.
Note: If you change the baud rate, make sure the baud rate of your terminal
is changed also.
After entering the baud rate, you are prompted for parity.
The DL20 ignores the parity bit, but is capable of generating it. If you
choose to set parity, you will be prompted for odd or even parity. If neither
odd or even parity is selected, no parity is set. A message displays showing
the parity in effect.
