3704/3705 Control Program This support is equivalent to that provided in Release 1 of Vft/370. The CP DIAL command and the TERftINAL APL ON and APL OFF command lines
are supported. However, Release 2 and above of Vft/370 provides
additional support: • Service programs and special eMS commands allow you to easily generate the EP control program in a CMS virtual machine. • The CP NETWORK command allows you to load or dump the 3704/3705 and
provides for automatic dumping and reloading if a fatal error occurs. Part 4. Generating the 3704/3705 Control Program 295
