[RTTY] TinyFSK modem for 45 and 75 baud

[Mark]

Well I was curious so I measured what I get.  All identical settings in n1mm/mmtty

Afsk.   33-34 ms
FSK motherboard based com port.  33-34 ms
FSK 8 port edgeport USB adapter. 46-48ms!

And you know it does sound different.  

In looking at others in the contest today I see quite a few stations at both ends of this range.
I had always figured the edgeport was equivalent to a traditional com port, but unless I 
can find another variable, that's not the case.

Anyone running edgeports who can confirm this?
