Details of each command are given in the table.
OSCLI
This call is used to select the IEEEFS by placing the address of the command line IEEE in
V (high byte) and X (low byte) and calling &FFF7 which indirects through &2M. The
command line should not start with an asterisk and must end with &OD. Any leading
spaces will be stripped.
DATA
When data is sent using the OSBPUT and OSBGET calls, strings are transferred
as type (&00) length and characters (in reverse order). When binary coded data is being
handled it is sent and received a byte at a time.
Example

Open COMMAND and DATA channels by using OSFIND
Execute IEEE commands eg CLEAR, REMOTE ENABLE etc by calling OSWORD
