Question About PBFAX8B

[Steve Bouffe]

Is it possible to run this in a win 3.11 dos box

I have tried it on an old 483 sx25 box.

If the window is active (the one with pbfax) it seems to work.

However when it's minimised, the fax transmission encounters an error.

Is it just that the old pc is running out of steam ?

Windows 3.x allocates less time to a background application, which can interfere with the timing of the fax transmission.

I use the following code to set a "critical section" during the fax transmission to stop Windows interfering with the the fax session timing.

        call Text2Fax(Fax)              ' No convert the file
        if Fax.FaxError then FinishedFax' Error occurred?
        if (istrue bit(pbvHost,8)) and (isfalse bit(pbvHost,5)) then    ' only if not in the IDE and Windows is running!
            asm MOV AX,&H1681
            asm INT &H2F
        end if
        call PBFax(Fax)                 ' Now fax the converted document
        if (istrue bit(pbvHost,8)) and (isfalse bit(pbvHost,5)) then
            asm MOV AX,&H1682
            asm INT &H2F
        end if
