This is 'cos most fax-modem-chip-firmware will only handle faxes at a
top speed of 19200/xon-xoff at best. If you plan to use your modem for
data-connections as well, you should set it to the highest possible
speed with RTS/CTS flow control, and let HylaFAX switch to a lower
rate when it receieves a fax. ie

    ModemRate:          38400
    ModemFlowControl:   rtscts

    ModemAnswerFaxBeginCmd: "<19200><xon>"  # lock line rate and flow-control
