CHAPTER 2 SETUP AND OPERATION

RPC-150 Page 5

4. Press < F2> to return to the immediate mode.

NOTE: Some versions of P C SmartLINK have pull

down menus or will operate differently. Refer

to the SmartLINK manual for the version you

are using.

Downloading programs

To practice downloading a program , type

NEW< return>

Perform the following when using PC SmartLINK:

1. Press the < F1> key to view the main menu.

2. SmartLINK has a buffer which is used to

temporarily store the program. If you followed

these instructions without exiting SmartLINK, the

previously uploaded program is in the buffer and

may be downloaded. However, lets assume you just

started SmartLINK. Press the L key to get the

program from the disk.

3. Enter the filename to get the file.

4. Press D to download the program.

5. Press the < F2> key to return to the program. You

can list the program by typing:

Other communications software

The following is general information when using another

terminal emulation program (Procomm, Windows

Terminal, etc.).

When uploading or downloading files, select ASCII text

format. XMODEM, YMODEM, or other formats are

not used.

CAM BASIC does not know when you are typing in a

program or if something else (laptop or mainfr ame) is

sending it char acters. The upload and download file

does not contain any special control codes, it is sim ply

ASCII characters.

Uploading programs is simply a process of receiving an

ASCII file. You or your program simply needs to send

"LIST" to receive the entire program . The default baud

rate (19200) is rather high. M ake sure your PC and

communications software can work at these bau d rates.

PROCOM M was tested on a 12 Mhz 286 PC and it

worked fine. Windows Terminal on the same PC had

problems at m uch slower baud rates.

Downloading a program requires transmitting an ASCII

file. CAMBASIC is an incremental line compiler. As

you type in (or download) a line, CAMBASIC compiles

that line. The time to compile a line depends upon its

complexity and how many line of code have been

entered.

CAM BASIC must finish compiling a line before starting

the next one. When a line is compiled, a "> " character

is sent by the card. This should be your terminal

programs pacing character when downloading a

program.

If your communications program cannot look for a

pacing prompt, set it to delay transmission after each line

is sent. A 100 ms delay is usually adequate, but your

CAM BASIC progr am may be long and complex and

require mor e time. A result of a short delay time is

missing or garbled program lines.

CAM BASIC sends out escape sequences to clear the

screen. T his sequence may appear as < -; on your

screen. Usually this is not a problem.

COM 1 on the RPC-150 does not recognize the CT S or

RTS lines. The CTS line is NOT pulled high on the

RPC -150. The effect of not rec ognizing these lines is

your PC or terminal cannot hold off the RPC-150' s

transmission. Converse, the RP C-150 cannot hold off

the host from sending it data. Set your terminal program

to not recognize or use the CTS and RTS lines.

Editing programs and program ming hints

Files uploaded or downloaded are simply ASCII DOS

text files. No special characters or control codes are

used. You may create and edit programs using your

favorite word processor or editor. Just be sure to save

files in DOS text form at.

A technique used to further program documentation and

reduce code space is the use of comments in a
