Version history file of Ethernet interface card IF-E1B

Legend:
+ Feature added
* Feature changed
- Bug or feature removed

v2.05
- MAC address was not unique for every card, so that using several units in a network rendered them to stop working

v2.06
* Keep-alive timeout of socket increased to 10min. (before: 10s)
+ Added termination character 0x0A to all response messages, in order to make it easier to fin the end of the message in message buffer

v2.07
- Corrected DATA:SET command, because object 54 didn't work as expected

v2.08
- MAC address problem solved that occured when updating the card's firmware

v2.09
* DHCP: DHCP functionality was an undocumented feature since v2.01, activated by accident. Now DHCP is turned off by default and can be turned on via the IF-E1B website, page CONFIG.
        The card then works as a DHCP client, receiving IP from a DHCP server, if there is any. In any other case, it will use the IP/network settings given by the user.

v2.10
* MAC adress: MAC handling now made explicit. In case the interface card can not get the MAC from the device, it generates a normal MAC from the device serial number, but always starting
			  with 00:50:C2 (EA reserved MAC address space). Result: even if the card does not use the MAC as printed on the card, the generated MAC should be unique and not interfere
			  with other MACs.
			  
v2.11
- SCPI command VOLT, when using the card in an electronic load, was not executed even if the load was switched to CV mode before

v2.12
- Corrected handling of termination characters. It is now OK to send CR, LF or CRLF after any command. The interface returns any command terminated by LF, as before.

v2.14
* Improved overall communication speed and stability
* Implemented better handling of erroneous command strings
* Improved DHCP functionality
