OSBYTE &03 (3) - Select output device
On entry, X=new output selection
On exit, X=old output selection
Controls which output device or devices receive the characters sent to OSWRCH.
The value of X is made up as follows:
| Bit | Meaning if set |
|---|---|
| 0 | Enable serial port |
| 1 | Disable screen drivers (overrides VDU 2 and VDU 6)
|
| 2 | Disable printer (overrides VDU 2 and bits 3 and 6)
|
| 3 | Enable printer (overrides VDU 3)
|
| 4 | Disable output to *SPOOL file
|
| 5 | Not used |
| 6 | Disable printer except for VDU 1 sequences (overrides bit 3)
|
| 7 | Not used |
This flowchart shows the flow of characters from the OSWRCH entry point to the output devices.
Common OSBYTE 3 settings are:
| *FX3,0 | normal state, serial disabled, VDU enabled, printer enabled by VDU 2, spool output if *SPOOL file open |
| *FX3,1 | normal output, also send to serial port |
| *FX3,2 | disable all output except printer port and any *SPOOL file |
| *FX3,3 | disable VDU, enable serial port and any *SPOOL file |
| *FX3,16 | normal output without copying to *SPOOL file |
| *FX3,18 | disable all output except printer port |
| *FX3,22 | disable all output |
| *FX3,23 | disable all output except serial port |
| *FX3,86 | disable all output entirely |
