Your interface can also be used with PTT control in CW by simply
setting the "Digital" port RTS to "PTT".  In addition, the three
transistor interface will work fine with a USB to serial converter
and MMTTY's EXTFSK driver.

The interface is essentially the same as documented by AA5AU on
his RTTY web site:  http://www.aa5au.com/rttyinterface.html
