- ==============================
-
-
- I will be the first to admit that it took me about six weeks to
- figure out how to get my MEX terminal program to run in a functional
- usable way despite the fact that I had already mastered several C-64 and
- C-128 communications programs. The biggest reason for this is due
- mainly to the cryptic documentation (from a beginning telecommunicators
- standpoint) and the Command Line orientation of the program versus Pull
- Down Menu Structure of the more GRAPHICS oriented Native 128 and 64
- Software.
-
- However, these initial problems aside MEX is a Powerful piece of
- Communications Software and, when used with your Ram Expansion Module
- can allow you to download up to half a megabyte of information in one
- continuous block which is great for transferring databases and large
- files not limited to the smaller disk and Ram buffers sizes of the C-64
- C-128 Modes of your computer. Using the Ram Expansion Module and Mex
- gives you the Telecommunications power of computers costing hundreds if
- not thousands of dollars more than your C-128. Once you master a few
- simple commands you will be able to take advantage of this feature
- packed terminal program and this article is designed to give the basics
- to getting up and running.
-
-
- Basically all Telecommunications programs are designed to perform
- the same functions that is; Connect to a host computer and transfer
- information. More advanced functions will include the use of buffers to
- temporarily store data which may be edited before transferring it to an
- output device (Screen, Disk or Printer). Additionally most modern
- telecommunications programs will feature Auto Dialing and custom
- configuration abilities as well. MEX offers all of these features and
- if you have done these things with other telecommunications software you
- will be that much ahead of the game in learning how to use MEX.
-
- Mex is an evolutionary program to the extent that it follows the
- structure and commands of earlier CP/M Communications software. (MODEM7
- is in my mind). In fact some of the IMP commands are similar to those
- used in MODEM7 and MEX. The point here is that like in 128 and 64 Mode
- once you have learned to use one type of term program it is generally
- not to difficult to figure out others and the same holds true for the
- CP/M side so keep an open mind and this should help you to get it
- together much quicker.
-
-
-
-
- Accessing MEX
- -------------
-
- To access MEX from CP/M, make sure the MEX.COM program is in the
- logged drive (m:Drive if you're using it in your Ram Disk) and type MEX.
-
- That's it. MEX
-
- To get out and return to DOS just type CPM.
-
- You will exit MEX and return to DOS.
-
-
- Once inside MEX like other terminal programs you are not
- automatically in terminal mode but are in a holding area so to speak
- where you may select a program function you want to perform, eg. Set
- system parameters, send or receive files, open a capture file, enter
- terminal mode, etc. This is no different than being presented with a
- main menu in one of your Commodore term programs except with MEX they
- forgot to present you with the menu. To get help you will need to ask
- for it which is what the command line prompt is used for. Type in a ?
- at the prompt and you will be presented with a list of commands you may
- use from NON/TERMINAL mode. Some of this should start to look Familiar?
-
-
-
- Accessing Terminal Mode.
- -----------------------
-
- To Access Terminal mode type "L" at the MEX Prompt. This will put
- you in local echo mode suitable for communications with GEnie. Typing a
- "T" will put you in terminal mode with no echo and you and you won't be
- able to see what your sending.
-
- To get help in terminal mode press the escape Key and then the ?
- key. Note: Using Escape sequences is a little different than executing
- control key sequences. Don't hold the keys down together at the same
- time like executing a control key sequence in WordStar, instead press
- the keys separately.
-
-
-
- Dialing a Number
- ----------------
-
- To Dial a number out type ATDT (if you're using a Hayes Compatible
- modem such as a Commodore 1670) preceded by the number you are calling
- and then press the return key.
-
- Eg. ATDT5796440
-
- The ATDT must be typed in capital letters or your modem won't
- recognize that you are sending it a command.
-
- The program will then dial the number and if a carrier is detected
- within in the proscribed delay time the computers will hook up.
-
- Once you have logged on to the system you can follow its prompts
- for the most part and begin your telecommunications session.
-
- NOTE: The program is capable of autodialing which can be accessed
- from non terminal mode using the CAL command however we're not going to
- get into this in this article for the sake of KISS (keeping it simple
- stupid).
-
-
-
- Capturing Text
- --------------
-
- Many times online you will find that you would like to retain the
- information being displayed to your screen. With MEX you may capture a
- block of text by creating a buffer file. To do this you must exit
- terminal mode briefly. This is done by first hitting the escape key and
- then the E (for Exit) key. Again, Press the two keys separately and you
- should find your self back in non-terminal mode staring at a MEX Prompt.
- At this point creating a buffer file is as simple as pie.
-
- Type,
-
- l filname.doc
-
- whereas l = (return to local terminal mode)
- filename.doc = (Any legal CPM filename.)
-
- and then press return.
-
- This will send you back to terminal mode were you will get a
- message telling you that the ASCII buffer has been turned on. Also any
- time that you see a line starting with a (:) it is being captured.
-
- To toggle the buffer on and off in terminal mode press the Escape
- key and the U key to turn the capture off and Esc S to Start capturing.
-
- Note: You can't turn the capture on and off if you haven't opened
- a buffer file.
-
- Other Nifty Esc Sequences to know are:
-
- Esc @ to send a break command to the Host computer
-
- and
-
- Esc T to transmit a text file from Disk or Ram Disk to the host
- Computer, for uploading pre-written GEnie E-Mail.
-
-
- Transferring Binary Files.
- -------------------------
-
- Transferring Binary files is just as simple. First you must exit
- terminal mode as above (Press Esc E). The protocol is essentially the
- same here, type either an S for Send or R for Receive followed by a
- space and then the Drive/User# followed by the file name.
-
- For example to receive a file named SMART.COM type,
-
- R A0:SMART.COM
-
- To Transmit the same file type,
-
- S M0:SMART.COM
-
- Note: If you do not designate drive and user specifications MEX
- will assume the default drive and user specs.
-
-
- Mex will open the file and display the block number being
- transmitted or received as the case may be during the transfer. When
- the transfer has been completed you will be returned to the non-terminal
- mode where you must instruct the program to return you terminal mode to
- regain communications with the host computer to download another file,
- log off, or whatever.
-
- Well, that's it, the above will get you started and after you've
- begun to perform these basic functions you may be able to understand the
- more cryptic instructions in the MEX Users Guide and maybe you won't but
- I think this will open the door for most of you out there.
-
- If you have questions I'll be glad to help in any way I can as I am
- sure Michael Mantino (GEnie Commodore/CP/M SYSOP) Michael.M will in a
- lot of cases offer his valuable assistance as well.
