151/I16V Print standard header or trailer:
Used to print standard headers/trailers. If headers/trailers are disabled
through the BANNERS, HEADON, or HEADOFF commands, this control code is
invalid.
PM (privileged mode) is required to use this option.

parm1 =1 is supported. Valid values are:
1 Specify terminal type or printer type file:
Specifies a new terminal type or printer type file for use
with a device. The specified file may be created through
the TTUTIL utility. The name of the terminal type or
printer type file is passed in buffer , with the length of
buffer set through the length parameter. If this call is
issued against a device connected through PAD, CCE (2)is
returned and the terminal or printer type associated with
the device is changed, but the device operates as if no
device control action took place.
2 Set read timeout value for next read:
Sets a timeout value to be applied to the next read request
in seconds. If the timer expires before the next read is
terminated, the read data is transferred to the buffer and
the read reply returns a software timeout error status
