Ed, 

As I responded to Froggy on the microHAM support e-mail:

This not a "fault" of any software or hardware ... simply a lack 
of a common interface.    

The potential solutions are: 
  1) the ability of Writelog to use DTR for "software FSK" 
  2) adding the capability to map TxD to DTR in microHAM Router 
     to support the Writelog Software FSK 
  3) modifying the (third party) MMTTY plug-in for Writelog to 
     allow specifying the output (PTT) port directly in the 
     plug-in (using MMTTY.INI) 
  4) Adding EXTFSK as a choice in the RTTYrite "Ports" list so 
     EXTFSK can be passed to the plug-in. 

In the meantime, USB Interface II will work with WriteLog and 
the MMTTY plugin if MMTTY is configured for AFSK (Sound + COM-TxD). 

73,
