[SD-User] SD-10.23 and keyer

[Fred Ockert]

hallo all,

after some changes
a simple (2 transistor) Icom-interface works fine on my IC737A (renamed 
ic738.sd to ic737.sd - changed port-code to 0x3c Hex)
Solution: set all RTS,DTS,DSR pin's, not needed to HIGH level, these 
pin's are needed as power supply !

but found some myserious... SD did not key the line on my LPT1 port...
solution found in sdconfig
setting sd-sidetone=0 - it started to key
manual says something sd_cwtest, switching speaker<--> PTT-line
hmmm - but how to swith sidetone on/off ??
