Your computer accesses a
different port each time you do a
soft reboot, so the modem is
often not found

Add the following statement to your
CONFIG.SYS file before the C&SS driver
statements
device=c:\mhz\clrcom.exe
n
where
n
is the COM port assigned to the
modem. If this file is not in your C:\MHZ
directory, copy it from
