Dear Ladies and Gentlemen, Man (4) termios states The CCTS_OFLOW (CRTSCTS) flag is currently unused. Is this likely to change in the near future ? I am using SMSLink (http://www.styx.demon.co.uk/smslink/) and libmodem-1.5 to send critical service notifications from Netsaint (http://www.netsaint.org) to an SMS modem (a Wavecom WM02). This works Ok but there is message loss if the message rate exceeeds 12/minute (my testing, not the rate of critical notifications). If libmodem uses hardware flow control (rather than XON/XOFF) the message loss is worse. I suppose that the real culprit is the application since 9600 bits per second is much faster than 12 * 160 * 8/60 bits in a 160 byte SMS message /second. Would anyone care to comment on hardware flow control ? Thank you, Yours sincerely.
