lpt 12845B 2607 line printer
|
||
|
||
19-Nov-04 JDB Added restart when set online, etc.
|
||
29-Sep-04 JDB Added SET OFFLINE/ONLINE, POWEROFF/POWERON
|
||
Fixed status returns for error conditions
|
||
Fixed TOF handling so form remains on line 0
|
||
03-Jun-04 RMS Fixed timing (found by Dave Bryan)
|
||
26-Apr-04 RMS Fixed SFS x,C and SFC x,C
|
||
Implemented DMA SRQ (follows FLG)
|
||
25-Apr-03 RMS Revised for extended file support
|
||
24-Oct-02 RMS Cloned from 12653A
|
||
|
||
The 2607 provides three status bits via the interface:
|
||
|
||
bit 15 -- printer ready (online)
|
||
bit 14 -- paper out
|
||
bit 0 -- printer idle
|
||
|
||
The expected status returns are:
|
||
|
||
140001 -- power off or cable disconnected
|
||
100001 -- power on, paper loaded, printer ready
|
||
100000 -- power on, paper loaded, printer busy
|
||
040000 -- power on, paper out (at bottom-of-form)
|
||
000000 -- power on, paper out (not at BOF) / print button up / platen open
|
||
|
||
Manual Note: "2-33. PAPER OUT SIGNAL. [...] The signal is asserted only
|
||
when the format tape in the line printer has reached the bottom of form."
|
||
|
||
These simulator commands provide the listed printer states:
|
||
|
||
SET LPT POWEROFF --> power off or cable disconnected
|
||
SET LPT POWERON --> power on
|
||
SET LPT OFFLINE --> print button up
|
||
SET LPT ONLINE --> print button down
|
||
ATT LPT <file> --> paper loaded
|
||
DET LPT --> paper out
