[GreenKeys] Changing speeds on a Lorenz Lo-15b

[Fred Sonnenrein]

Hi Jeff,

nice to read that the number of interested enthusiasts for the i-telex 
increase.

The attempt to modify the printer for 50 / 45.45 Baud selectable is a 
nice challenge, but is not really necessarry to join the i-telex-group.

The i-telex ethernet interface collect each 5 data bits and send them as 
a "byte" (or a packet of more than one) over the world wide web.

So if your i-telex equipment is "adjusted" to 45.45 Baud, you can use 
the teleprinter with i-telex as well as RTTY.

And you will be able to 'talk' to other i-telex-members with 50 Baud 
teleprinters without any change to your equipment.

Best regards,

Fred
