I've noticed in a BASIC program that the ENTER command, as described in the Basic manual page 2-47 to 2-48,

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.

Thanks!
Guess it must have been something lost from the terminal serial driver to
the terminal network driver.
