Well, know the details before changing the code. 8-). The only *possible* way this cruft would be necessary is if the modem keeps DCD asserted, ignores DTR, or there is a driver error. Or the modem implements the RS232 external clock signal... and you can fix that by not passing the signal on the cable.
