6-9
The ASCII 17 character can be changed to ASCII 16 for XON/XOFF sensitive
systems by changing the Base Station Setup. See Chapter 2; RF System Setup
for details.
If the Base Station receives five Addressing a Terminal not SIGNed On
messages in a row, it transmits the following message to the Terminal and shuts
down: (it will recognize a reinitialize command (*@EOT) from the host though)
Base Shut Down
Due to Host Logic
Error
Check your program for the sequence error before starting again. The host
program will have to reinitialize the Base Station or you will have to cycle
power on the Base Station and have the Terminal Sign On again in order to
continue.
Sequence Error Message
The one-for-one “host prompt/terminal response” protocol must be observed by
the host program at all times. The host cannot send a second data entry prompt
until it has received a response to the first data entry prompt. If it does, this is
considered a Sequence Error. If the Base Station receives a command that is
out of sequence, it sends the following message back to the host:
Byte position Function Possible values
1 RF Terminal ID 0-F
2+ Sequence Error DC2 (ASCII 18)
Last Termination of message CR (ASCII 13)
If the Base Station receives 5 Sequence Error’s in a row, it transmits the
following message to the Terminal and shuts down: (the only host command that
it will receive is *@EOT)
Base Shut Down
Due to Host Logic
Error
Check your program for the sequence error before starting again. You will have
to reinitialize the Base Station by host program control (*@EOT) or manually
cycle power on the Base Station and have the Terminal Sign On again in order
to continue.
Illegal Command
• When a terminal receives an illegal statement from the host, it will display the
entire statement on the terminal. Once the ENTER key is pressed on the
terminal, the terminal sends a “?” back to the Base Station.
