I have been running NT4 with procomm 4.8 and an external modem, connected to com1. The modem is a 300-2400 bps and works fine. I have been given a new XP pc and have installed procomm. If I connect to a 2400 bps site there is no problems, however if I connect to a 300 bps site the modem answers and I some times recieve a character or two, but I am unable to communicate. If I enter modem command mode and dial using ATDT this works fine. Is there any known problems with XP and Procomm working at low speeds?
