Howdy all,

I'm having trouble with the following code.  I can't seem to get it to
open the modem on COM3:.  After exiting the loop, it just hangs at the
"DEF SEG = 0" line.  (At least that's what QB4.5 says when I
Control+Break.)  I even compiled it and tried it outside of the QB4.5
environment.  Any help would be extremely appreciated!!!

=========================> Cut here <=========================

DEF SEG = 0

byte1% = PEEK(&H400)   'Save old info
byte2% = PEEK(&H401)   'Save old info
byte3% = PEEK(&H404)   'Get current COM3 info
byte4% = PEEK(&H405)   'Get current COM3 info

POKE &H400, byte3%     'Stuff COM3 base address into COM1
POKE &H401, byte4%     'Stuff COM3 base address into COM1

DEF SEG
'
'  Put your code here
'
PRINT "Opening COM3:"
OPEN "COM1:2400,N,8,1" FOR RANDOM AS #1 LEN = 256
PRINT "Calling 555-1212"
PRINT #1, "ATDT 555-1212"
PRINT "Waiting for keystroke..."
DO
LOOP UNTIL INKEY$ <> ""
PRINT "Returning base addresses to normal."
CLOSE 1

DEF SEG = 0          'Hangs up here

POKE &H400, byte1%   'Reset old COM1 base address
POKE &H401, byte2%   'Reser old COM1 base address

DEF SEG
