No, we are not talking about ANY Router command.  microHAM 
interfaces (DigiKeyer, microKEYER, microKEYER II and MK2R/MK2R+) 
can generate FSK from a PS/2 keyboard attached to the interface 
IF the transceiver is in RTTY (FSK) mode.  Unfortunately, the 
K3 reports its "Digital" mode as DATA A (AFSK) unless the K3 
response set is used.  

As I've stated several times, Router does not change the CAT 
mode (form of the IF response) because it might "break" any 
software that requires specific responses to the DS and FW 
command.  

This is not a matter of Router's programming ... it is a 
case where 1) the K3 does not report the information needed 
and 2) once the user has changed the mode of the K3, that 
change does not survive a reboot. 

The most logical solution would be to make "K31" persist 
across reboots and/or make the "d" byte active in the auto- 
information (IF) reports.
