Help!
I'm trying to redirect printer output from LPT1: to COM2:, but am
having no luck. Running under MS-DOS 3.2, I enter:
MODE COM2:1200,e,7,2,p
MODE LPT1:=COM2:
DOS responds saying COM2: is initialized, and LPT1: is redirected
to COM2:, yet whenever anything is sent to LPT1:, a device error
occurs (timeout error). If I send directly to COM2: everything
is hunky-dorey. Any clues? Am I cursed to never use anything that
ASSUMES all printing is done off LPT1? Shall I just go buy a new
Bleeding printer?

Newsgroups: comp.sys.ibm.pc In-Reply-To: article <19981MRS@PSUVM> of Fri, 11 Sep 87 21:16:29 PDT I tried to mail this directly but my mailer doesn't seem to know how to get to BITNET. So I'm posting this instead. Re: Trying to use a serial printer with MS-DOS 3.2 I, too, have had the same problem. I have talked with Microsoft about it and it is a confirmed bug in 3.2. I have also tested PC-DOS 3.3 and found it to be a little better but still has problems. In my investigations it seems to depend on which INT 21 function is used by the program. If the old 05H and 09H calls are used you're hosed. If the program uses Handles through function 40H then the serial printer will work fine. My solution is to boot MS-DOS 3.1 when the program uses functions 05H and 09H, which, of course, is a real pain. Yes, 3.1 does not have this problem. Eventually I will cave-in and buy a parallel printer as that is what DOS seems to like best. Dave Guggisberg Hewlett-Packard Corvallis, Or hp-pcd!daveg
