Serial Device Tester Description:

The Serial device test utility is designed to assist with the debugging
of serial communications with new devices as well as the development
of the PC based application that interacts with the remote device.
Some of the features include the ability to transmit data as ASCII,
Decimal, or Hex values as well as viewing the in bound data in both
ASCII and Hex simultaneously, creating wrappers that are used in
conjunction with the data sent, creating log files of the session for later
viewing, and easily appended carriage return and line feeds. Features
currently under development include the ability to handle constantly
streaming data, preset data for transmission, The ability to program auto
responses for use as ACKS, added tool bars, and Checksum/CRC capability.

Version 1.1 fixes 2 major bugs -- a crash that would occur on some non-US
versions of Windows as well as fixing how the Data Terminal Ready (DTR) line
is handled. Some GUI features have been enhanced as well.
