- param <iface> [<param>]
- Invoke a device-specific control routine. A simple 'param
- <iface>' will give a list of available parameters, and their current
- values, for the interface <iface>. <param> can be the literal
- description of the parameter.
-
- On the serial interface, this sends control packets over the
- serial port. Example, 'param port1 txdelay 255' will set the keyup
- timer (type field = txdelay) on the KISS TNC configured as port1 to
- 2.55 seconds (255 x .01 sec).
-
- On the radio ports, all timing parameters use a 10ms tick count,
- e.g. 30 means 300ms. Some commonly used options are:
-
- slottime - the channel access slottime
- maxwait - maximum time to defer transmissions
- txdelay - keyup delay before sending data
- persist - the csma persistence (range 0-255)
- maxkey - maximum time to allow transmitter to be keyed
- (range 0-65000)
- txtail - time to keep transmitter keyed up after end of packet
-
-
- NOTE: the txtail parameter is NOT settable, but is always 4
- characters duration at the port's speed. The value shown is
- calculated from the speed given when the interface is first attached.
- When you use the trick previously mentioned to allow interchanging of
- DE1200 and DE9600 modems, the txtail shown when a DE9600 modem is used
- is WRONG. However, the actual value used is still correct.
