Base Shut Down 
Due to Host Logic 
Error 
 

You can re-initialize the terminal by sending *@EOT or by powering the base off and back on. 
 

Automatic Check Back 

When a terminal checks back in to see if there is a change in instructions, the host can send back the same prompt or send back a 
new prompt. The check back occurs according to the time specified in the Terminal's setup, (specified in increments of 5 sec-
onds). When a check back occurs, the Terminal clears the screen of the current prompt, and sends back the following message: 
 

   

Byte position

 

   Function 

   Possible values 

1 

RF Terminal ID 

0-9,A-Z,a-z,-= 

2+ 

Check Back 

BEL (ASCII 07) 

Last 

Termination of message 

CR (ASCII 13) 

 

 

Base Station Initialized Message 

Whenever the Base Station is powered up, it sends a message back to the host as follows: 
 

   Byte position 

   Function 

   Possible values 

1 

BASE ID 

*

 (

Base ID is fixed

)

 

2+ 

Base Initialization 

DC3 (ASCII 19) 

Last 

Termination of message 

CR (ASCII 13) 

 

Since ASCII 19 is XOFF, the ASCII 19 character can be changed to ASCII 20 for XON/XOFF sensitive systems by changing the 
Base Station Setup. See 

Chapter 2; 

RF System Setup

 for details. 

 
The 

Base Station Initialized

 message is provided so that the host will know that there has been a power interruption on the Base 

Station. When a serial device powers up, the first byte transmitted is often garbage. QBASIC handles the garbage character with-
out incidence, but GWBASIC does not unless ON ERROR GOTO is used to trap the error. Be aware of this potential garbage-
byte problem in your programming. To isolate and test for the problem, power up the Base 

without

 the serial cable connected. Af-

ter you power the Base up, plug in the serial cable. You will 

not

 see the “

Base Initialized

” message but it should not matter when 

testing for the garbage data. 
 
If a terminal is signed-on to the system, and the base station is re-initialized, the following message is sent to the terminal: 

Base Reinitialized 

X 

Cycle Power on RF 
Terminal and Sign-on 
again to Restart_ 

 

where 

X

 is either a 

P

 (base initialization was power-related) or 

H

 (base initialization was host-related). 

 
 
 
 
 
 
 
 
 
 
 
 
 
 

Control Keys for Possible Programming 

There are some keys on the RF Terminal keypad that when pressed, can transmit special ASCII characters back to the host pro-
gram. This feature might be used by a programmer to allow the operator to review transactions. 

You can use these keys for spe-
