  1. Because there is no DTR wire (modem pin 20) from Pilot. Pilot can simulate DTR line but this is not used at this moment (needs a pull-up)
  2. This way we can not dial without a known dial tone if needed (like in some areas out of USA)
  3. There no reason for this setting. Using X4 modem will dial as soon as it detects a known dial tone. Modem will not dial without a known dial tone (no good outside USA).

I only used TX, RX and signal ground so there is no hardware flow control. I don't seem to have any problems. I have successfully transferred 77 mail messages in one session so it seems to run OK even for long transfers. This is defiantly not the modem I want to keep for mail it is much too slow but it works that was my intention to make it a truly portable e-mail machine. I will probably raffle this off when I get my new modem, I'm sure there is some poor unfortunate soul out there that spent his last dime just to get his Pilot. Maybe someone will write a fax app so I can try the fax in this unit. If you have any questions on this project e-mail me.
