[RTTY] infos on usb to serial

[Joe Subich, W4TV]

Noel, 

Many of the generic USB to serial adapters do not do FSK 
because their chips no longer include provision for 5 bit 
codes and data rates below 300 bps. 

There are a couple of easy solutions ... first use EXTFSK 
with MMTTY (used in N1MM Logger and WinTest) or use "software 
FSK" with Writelog.  Both applications will allow FSK with 
the generic USB -> serial adapters.  N1MM Logger happily 
supports FSK, PTT and CW on a single adapter if configured 
properly.  

The second solution ... just say I have a commercial interest 
in it <G>.

PS. the EXTFSK solution also works with WinWarbler (DXLab Suite), 
    Logger 32, DX4Win, and other "day to day" logging software 
    that use the MMTTY engine for RTTY.
