Xon/Xoff Modems
Some early modems assume software flow control (Xon/Xoff) between the computer
and the modem. Modems with this design send extra characters during and after the
transmitted data. The service processor cannot accept these extra characters. If your
configuration includes such a modem, your functional results may be unpredictable.
The sample modem configuration files included in this appendix do not support these
modems, so custom configuration files are necessary. Anchor Automation 2400E is an
example of such a modem.
If you experience unexplainable performance problems that may be due to Xon/Xoff
characters, it is recommended that you upgrade your modem.
