Creating a printer port, help needed

Show all headers | View raw

I'm trying to create a printer install GUI, mainly for CUPS printing
at the moment (although I may extend it to be more general later on).

It almost works, but the problem I've run into is installing a printer
port programmatically.

The problem is this: I can create a new port (e.g. 'CUPS2') by adding
the right entries to OS2SYS.INI, but the port is unusable until the
system is rebooted.  (Before that, the printer object shows an error
message that "printer is not accepting data".)

I've also tried using the OS/2 response-file printer installer (which 
I use to create the actual queue and printer object) to create the 
port.  Unfortunately, the same thing happens.

Finally, I tried writing a simple program that uses SplCreatePort, 
and calling that from my script.  Same result.

Of course, creating a port works fine the "normal" way, i.e. going 
through the PM printer dialogs.  But that's a non-starter for an
automated installer, obviously.  

I strongly suspect that SOMETHING in Presentation Manager needs to get
flagged when a new port is added, that 


To make matters worse, I've found that after I've created ports in 
this way, opening a printer object's properties notebook has a nasty
tendency to randomly trap the system.  


Here's a REXX script containing my attempted logic:

It's written to use CUPS ports at the moment, but changing that to,
say, SLPR or SMB ports should be as trivial as changing a couple of
lines.
