Obvious question, but have you enabled rts/cts hardware flow control
on the MODEM as well. Also, some comm programs don't use the same
ioctl structure and may not be setting the rts/cts parameter
correctly. Check with stty -a </dev/ttyS??. If if isn't enabled,
then you'll have to enable it manually.
