dlytx Delay data packet transmissions
This command is used to set the delay between the last serial character
received by the radio modem and the next packet of data sent from the radio
modem.
Radio network traffic is reduced by delaying packet transmissions until there is
either a timeout of this delay period or there is enough data in the serial receive
queue to transmit a complete full length data packet.
The delay has no effect on the speed of transmission when data is being
streamed through the radio modem. It does however assist in lowering the
transmission rate for non-streaming data such as typing on a keyboard.
Command format:
dlytx [n]
where: n =
[4-255] This value is in units of 10 milliseconds. Therefore a value
of 4 is equivalent to 40ms, while a value of 255 corresponds to a
2.55 second delay. The default value is adequate for most
applications.
retry Data packet retry attempts
This command sets the number of retry attempts the radio modem makes to get
a packet sent to the remote unit.
A data packet or it’s return acknowledgement may not have been received. In
this instance, after a time out period, the packet is retransmitted. The packet is
retransmitted until either the appropriate acknowledgement is received or the
packet retry count is exceeded.
If the packet retry count is exceeded the data in the radio modem is discarded
and the radio modem re-enters the standby mode. Further data sent to the
radio modem will result in the radio modem attempting to once again reconnect
to the remote unit to transfer the data.
In areas of possible radio interference it may be necessary to increase the
number of packet retries.
When using the radio modem for a streaming higher layer protocol such as
ZMODEM or XMODEM, a low value for the packet retries should be used. This
is due to the protocols having their own internal timers for packet times outs.
Having a high number of packet retries in the radio modem can therefore result
in unpredictable results from the higher layer protocol.
The default value is recommended for most situations.
Command format:
retry [n]
where: n =
[1-63] This value specifies the number of attempts the radio modem
makes to try to send the data packet to the remote unit.
