- ADDITIONAL NOTES FOR THE "RU" RTTY UTILITY
-
- This program is a slightly modified from the original RTTYU program
- by KF4NB. It's operation is mentioned in the documentation for his
- RTTY program on this system.
-
- Changes to look for are:
-
- 1) Prompt for drive that has pix; with "B" being the default. Simply
- hitting enter will save having to type the "B:" every time when
- printing pix. If you want to override the default type "d:", with
- "d" being the desired drive.
-
- 2) Request for pix size - with "Small" being the default. This results
- in a much better picture. The matrix printers used are rather thin
- in putting ink on paper so the pix that look OK on a Teletype
- machine look weak and washed out on the IBM Grafix printer. In the
- Small (default) mode the pix look great!
-
- This change simply sends a printer modification command before the
- pix is printed. The command will set the printer to compressed
- print and 6/72 " line spacing (I think). This makes for a nice
- tight pix that looks fantastic. If you have another type of printer
- that can't handle this, use Full for full size pix or modify the
- basic RU program to suit your printer, and recompile. The basic
- version runs very slow with out compiling.
-
- 3) When the quote (') is sent I suppressed the corresponding "BELL" or
- annoying beep. Some pix have thousands of 's in them and running
- thru a pix can make the computer more annoying than the old noisy
- TTY machines we just got rid of!
-
- 4) Not a change - just a note: When you save a file you will be
- prompted for additional info regarding compression. If you say
- Yes then the file will be saved as compressed data. I have found
- that most pix will shrink to 50% of the original size. This depends
- how many redundant characters there are in a pix, of course.
-
- Another note, you can send the compressed pix right from your RTTY
- program as it will un-compress it as it is sent out. NOT necessary
- to un-compress with RU and then send it with RTTY.
-
- 5) For this program to operate correctly, a received RTTY pix must have
- been received with the RTTY program in "ART" mode. This is done with
- the ALT-A key while the RTTY program is running, but before a pix
- has started to be received. Of course, you will have hit F3 to
- receive a file to disk!
-
- A file that has been properly received for RTTY ART will have special
- characters added to each line for carriage control and line feed
- control. Those characters are listed below.
-
- Backwards "P" or paragraph symbol will cause a LINE FEED
-
- The "vertical arrows" will cause a carriage return.
-
-
- Note that if the pix has overline printing there will be the
- vertical arrows without the backwards P. This of course, will
- cause a carriage return with no line feed. The result is over-
- striking capability.
-
- 6) File sizes are listed below. Use to verify that the download
- is OK. This size should show up on a directory list on your PC.

- RU.BAS - 5338 bytes
- RU.EXEBIN - 22784
- PARMS.RTY - 175
