When modem receives a break from the DTE:
\K0,2,4 Enter on-line command mode, no break sent to the remote modem
\K1 Clear buffers and send break to remote modem
\K3 Send break to remote modem immediately
\K5 Send break to remote modem in sequence with transmitted data
When modem receives \B in on-line command state:
\K0,1 Clear buffers and send break to remote modem
\K2,3 Send break to remote modem immediately
