is a program to fully simulate the mar research 345mm Image Plate Detector
System. This program is useful to test, debug or demonstrate software to
operate the scanner and the base (e.g. mar345, scan345). Note, that there
are 2 versions of scanner electronics which operate differently. Accordingly,
the scanner driving program "mar345" comes in 2 versions. Program version
< 1.0 operates on scanners with serial numbers < 044. For marsim, accordingly,
there are 2 versions as well. Version numbers < 4.0 only work together with
version < 1.0 of program mar345!
Use BSD port <PORT> rather
than the default (4123 for program version < 4.0 and 4441 for all others).
After quitting marsim, the operating system may disallow usage of the same
communication port for a limited time period. To overcome this problem,
another port may be used, but also the connecting program (e.g. mar345, scan345)
then has to use the specified port. -s(wap) Swaps bytes when reading input
commands or sending status and data. This needs to be done if the driver
program (mar345) is run on SGI and marsim is run on DEC/Linux or if both
marsim and mar345 are run on DEC/Linux. This flag is only available for
program versions >= 4.0.
marsim has to be started before
starting its counterpart. marsim is a TCP/IP-server that listens to connection
requests to the given port. It accepts commands through a socket interface
and writes simulated scan data on the data port.
