The Basic/V ENTER statement does indeed use an FCONTROL 22 call to get 
the read timer.
However, when connected via Telnet/iX or VT, FCONTROL 22 will return a 
CCE condition code
but is essentially a NO OP. If you want to prove this, try your sample 
program on the system console
or a DTC connected terminal.
