When connected to an OCIA terminal, the RL 470 base/interface will attempt 
to transmit the data to the host. If the host is not prepared to accept data at that 
time (i.e., the host data buffer may be full), the RL 470 will try to retransmit the 
data for up to 3 seconds. If transmission is not successful, the data will be 
discarded, and the RL 470 will issue a transmission error.

This parameter allows you to increase the time the RL 470 will attempt 
transmission before discarding the data. You can select up to a 30 second delay 
in one second increments. During the time the RL 470 is attempting to transmit 
data, no new data can be scanned.

Selects the data transmission speed to the NCR 2152 POS terminal. Depending 
on the version of NCR 2152, selecting this option may increase the possibility 
of lost or mis-transmitted data.

The RL 470 base/interface communicates with the IBM 4683/84/4693/94 as a 
scanner device, and also as a magstripe reader device. The RL 470/IBM 4683/
93 magstripe communications can be enabled and disabled via this parameter. 
If the RL 470 magstripe capability is needed, this parameter should be enabled. 
If not, it should be disabled to avoid contention with any other magstripe 
reader which may be connected to the host.

This parameter is supported by IBM AT/XT/PS2 terminals only. The layout of 
some international keyboards differ from that of American keyboards. To send 
a given character, regardless of its physical location on the keyboard, enable 
this parameter. 

This parameter is used when International Keypad Emulation is enabled. 
Some IBM AT/XT/PS2s allow for faster transmission. With this parameter 
enabled, the RL 470 transmits at a faster rate. Not all IBM AT/XT/PS2s support 
a faster transmission rate.
