- * Utils.c: Miscellaneous support routines for xprzmodem.library;
- * Version 2.10, 12 February 1991, by Rick Huebner.
- * Released to the Public Domain; do as you like with this code.
- *
- * Version 2.50, 15 November 1991, by William M. Perkins. Added code
- * to update_rate() function in utils.c to avoid the Guru # 80000005
- * you would have gotten if you had decided to adjust the system clock
- * back during an upload or download.
- *
- * Mysprintf() function to replace sprintf() and proto code to use
- * libinit.o and linent.o library code was supplied by Jim Cooper of SAS.
- *
- * Version 2.61, 3 July 1993 Mysprintf changed to xprsprintf(), written
- * in Assembler, because under SAS/C the old code running not correctly.
- *
- * Version 2.62, 27 July 1993 build in variable Blocksize.
- *
- * Version 2.63, 30 July 1993 build in locale, by Rainer Hess
- *
- * Version 2.64, 3 Aug 1993 global vaiable Blocksize, now in
- * struct Vars, by Rainer Hess
- *
- * 4 Aug 1993 changes in update_rate() function because
- * it always GURU 8000 0005 on little files (testet with 2 byte-file)
- * when you send. If on receiver the file exists when receiver ask for
- * overwrite, the machine crash if you click overwrite on receiver.
- * Testet on Term 3.4 -> Ncomm 2.0, by Rainer Hess
- *
- * Version 3.2 11 Nov 1994 modifications to implement FTN operations
- * by Roert Williamson
- * Version 3.2 19 Nov 1994 version string added, XPR 2.001 support added
- * Version 3.5 Jan 1,1994 added rxtimeout, xpr2ext setup options
