Command Set 4-16
Short Prompt (SP)
The Short Prompt command allows the user to specify a desired short
prompt ASCII character. A two character hexadecimal value is used to
define the desired ASCII character prompt.
Note: Short Prompt command may be sent to the module in either normal
addressing or Extended Addressing mode.
The user-defined short form prompt is only recognized by the module when
the module is in the Extended Addressing mode. See chapter 7 for details
on the Extended Addressing mode.
Avoid using the following hex codes $00, $0D, $23, $24 that are ASCII
characters NULL, CR, #, $. Using these codes for prompts will cause an
error when opening a channel in Extended Addressing mode.

Write Enable (WE)
The Write Enable (WE) command must precede commands that are write-
protected. This is to guard against accidentally over writing valuable data in
the module’s EEPROM. To change any write-protected parameter, the WE
command must precede the write-protected command. The response to the
WE command is an asterisk indicating that the module is ready to accept a
write-protected command. After the write-protected command is success-
fully completed, the module becomes automatically write disabled. Each
write-protected command must be preceded individually with a WE com-
mand. For example:
Command: $1WE
Response: *
Command: #1WE
Response: *1WEF7
Command: {01WE
Response: *
