Bug Fixes & Change History
Version 1.06b
Added “seropt” command to support serial data protocols of 8n1, 8n2, 8o1, 8e1.
Broadcast mode now does not enter standby. This elminates operational problems associated with link establishment.
Version 1.05a
Added acknowledged point-to-multipoint operating mode.
Added support for multimaster operating mode.
Added “addr” command to support on the fly address changing in support of point-to-multipoint mode.
Added parameter “slave” to the ptpmode command.
Added the parameter “mmaster” to the ptpmode command.
Fixed the problem of the ‘+++’ sequence being transmitted when entering the configurator.
Version 1.04a
Fixed problem in broadcast multidrop mode whereby the packet sequencing number, used in point-to-point mode, was not being
reset properly. This resulted in loss of the first data packet when receiving from a different polled remote modem.
Changed “signon” message function to also stop the signon message being displayed in the configurator, when signon is set to
off.
Added command “ser” to display serial number information in the configurator.
Added command “ctime” to allow setting of the connection duration.
Version 1.03a
Added adaptive back off for data packet retries. This removed the 1 second delay before packet retires. Effectively speeded up
transfers in noisy environments.
Added “rptmode all” to repeater mode. This now allows all packets regardless of unit and site code to be repeated. This is in
support of the “rptmode on” setting which only repeats packets of any unit address but only with a specific site address.
Reduced the “dlytx” default setting to 5 (x10ms).
Version 1.02a
Updated Xon/Xoff flow control and added end-t-end flow control between modems.
Version 1.01b
Removed support for 28800 bps.
Version 1.01a
Added 600 and 115200 baud support.
Added “airspd” command
Added “remote” command, which enabled remote over-air configuration.
Added “ptpmode” command, which enabled selection of broadcast-multidrop mode.
Changed crystal frequency allow more accurate and reliable baudrate generation.
Fixed packet addressing in diagnostic commands.
