Closer to Ril 482, sturdier server
- Indications as in El L: FlÜM on the protected point, VsM only after end position, ZFM goes out after release.
- Substitute signal only with a secured path; overlap release counts from occupation before the target signal.
- New TA/NA indicators (day/night signal voltage), switch with TE and NE.
- Sturdier server: dropped connections are detected faster, abuse is limited.
- After a reconnect the printer log, tutorial and notices are kept; F1/F2 no longer open the browser help.
