[net.micro.pc] How do you set switchchar on the AT?

mel@pegasus.UUCP (Mel Haas) (12/29/84)

The "switchar=-" in the config.sys file doesn't work, and I
can't find anything else in the manuals on how to do it.  A bit
of debug probing finds a code fragment at 017D:1A88 that returns it
as in the INT 21 call 37, and another fragment at 017D:1A8E that sets
it.  I can't seem to find what INT 21 call sets it.  The character is
located (on the AT I use) at 017D:0128, so a jam of 2D there works, but
is a kludge.  Help please.   Thanks.   Mel Haas   ihnp4!pegasus!mel

Under MSDOS 3.0:

To set the switchar:
   Call with ah=0x37, al=1, dl=desired switchar (typically '-')
   
To find out the current switchar:
   Call with ah=0x37, al=0, dl returns switchar.
