Compucom Speedmodem with RBBS-PC Bulletin Board Software

 Using the Compucom Speedmodem with RBBS-PC Bulletin Board Software:


This is by no means a technical document on all the different ways to

initialize your CompuCom Speedmodem for RBBS-PC, but a SIMPLE guide...


oo ..Be sure the Speedmodem ROM version is at least 2.51. Type ATI3...

\/ ..from any communications program in TERMINAL mode for results...

   ..EXAMPLE: (c) Copyright CompuCom 1990 V2.51


oo ..RBBS-PC is only capable of utilizing com-port 1 through 2 

\/ ..because of limitations within basic. This can be overcome with 

  ...the use of a fossil driver as described in the RBBS 

  ...documentation. Check your com port, the factory setting is 

  ...usually 4, so have fun with the jumpers!


oo ..Com 3 or 4 REQUIRES a FOSSIL. Setup your com-port correctly...

\/ ..Refer to your Remote Access documentation, X00.SYS example below.

   ..Modify CONFIG.SYS with the line, refer to DOS if needed...

   ..DEVICE=C:\X00.SYS E T=2048 R=2048 1=2F8,IRQ3 B,1,19200...(For Com2)


oo ..Install RBBS as recommended. Run CONFIG.EXE and make the...

\/ ..following choices...


oo ..Hold the SHIFT and press F2...

\/ ..Choose 225...


225. Set the modem commands


oo.....................................................................

\/.PLEASE NOTE: RBBS 17.3b has a bug when choosing a HAYES compatible..

...default modem...                                                 ...

...RBBS will actually write a Q0 at this location _____________     ...

...I do not know why, but just be sure to check that         ||     ...

...Q0 is in the EXACT location as below                      ||     ...

...The H0 is necessary for the modem to hangup               ||     ...

...AT&F2+F*H2%C0 can be substituted with other variations    ||     ...

...as recommended in the Speedmodem manual                   ||     ...

...Lines 2 and 7 do not seem to have the above mentioned bug ||     ...

                                                             ||

         Currently Specified Modem Commands are:


1. Reset the modem                : AT&F2+F*H2%C0S0=1&C1&D2V1Q0M0X1H0&W

                                         ^^Not on CompuComs after 4/1/91

2. Initialize the modem           : AT&F2+F*H2%C0S0=1Q0X1&C1&D2V1M0H0&W

                                         ^^Not on CompuComs after 4/1/91

   Note: Item 2 MUST contain one of the following:

            S0=001  (to answer on 0 rings)   ...................

            S0=254  (to answer on >0 rings)  ...REFER to RBBS...

            S0=255  (to answer on >0 rings)  ...Documentation...

                                             ...S0=1 works OK...

3. Count the number of rings      : ATS1?    ...................


4. Answer the phone               : ATA


5. Take the phone off the hook    : ATH


6. Clear the modem's firmware     : AT&F


7. Initialize modem's firmware    : AT&F2+F*H2%C0S0=1&C1&D2V1Q0M0X1H0&W

                                         ^^Not on CompuComs after 4/1/91

8. Write to modem's firmware      : AT&W


    Command to change (1 to 8), CR to end, or 0 to reset to defaults


oo ..Press ENTER when finished...

\/ ..Some settings below (***) are not critical...


        RBBS-PC Version 17.3B Configuration  Page 12 of 17

221. Communications port--- COMx (1 or 2, up to 8 with a fossil)

***. # of seconds to wait for modem to initialize - 3

***. Seconds to wait before issuing modem commands- 2     ...REFER..

224. Number of rings to wait before answering ----- 0..oo....to.....

225 (see above)                                        \/ ...RBBS.DOC

227. Issue modem commands between rings ----------- NO    (Yes???)

228. Baud rate to initially open modem at --------- 19200

***. Log off user who are idle for ---------------- 180 seconds

230. Are you using a 'DUMB' auto-answer modem? ---- NO

231. Initialize modem firmware for RBBS-PC.           ...AFTER 225...

***. # seconds to wait after dropping DTR --------- 3

***. File with PROTOCOL definitions --------------- C:PROTO.DEF

***. Always check caller for AUTODOWNLOAD support - NO

***. Require non-ascii protocol for BASIC files --- YES

***. Recycle if no calls are received within ------ 15 minutes

237. Leave modem at initial baud ------------------ YES

         RBBS-PC Version 17.3B Configuration  Page 13 o


241. Restore initial parms. after change to N/8/1 - NO

***. Minimum baud required of new callers --------- 0

***. Minimum baud required of old callers --------- 0

244. Modem flow control uses Clear-to-Send (CTS)--- YES

245. Modem flow control uses XON/XOFF ------------- NO

***. Seconds to wait for carrier after answering -- 30


oo ..*H2%C0 can be substituted with other variations...

\/ ..as recommended in the Speedmodem manual...


oo ..If using the COMBO, add +F to the Initialization string unless New

     ROM after 4/1/91

\/ ..turns fax off on the COMBO, returns ERROR on the CHAMP...


Dialing out:


oo ..RTS-CTS ON, ALL BAUD at 19200, AUTO BAUD DETECT OFF...

\/

  ...When using a long distance carrier with the Speedmodem...

  ...call your LD customer service and ask if a "carrier code"...

  ...is needed for proper "bandwidth" on "asynchronous" connections...


oo ..An example where this code is needed is the US Sprint...

\/ ..FIBER OPTIC NETWORK, to access a ""full-bandwidth" line...

  ...the code 10333 is needed, that is dial 10333-1-800-000-0000...

  ...this ensures that the FULL bandwidth is available to you...

  ...otherwise, a sudden "No carrier" can result...



Well, this by no means covers all the ways to use RBBS with a Compucom

Speedmodem. But it should help you initially (pun?). If all else fails,

don't forget to read the doc's!

EDITOR'S NOTE: I have only compiled this list.  I claim no responsibility for errors, discrepensies, bogus entries, repeated or contradictiory entries, spelling or grammatical errors, or governmental action against those in possession of this list. Thank for for your support! THE PREMISE: Last year, I attended a Science Fiction convention during which I discovered (along with other things) that the makers of the recently-demised TV series War of the Worlds, had a scene in the very first episode, where the original Martian war machines were found mouldering in a LA warehouse.  For fun, the special effects folk labeled one of the boxes in the warehouse 'Ark of the Covenant', indicating that it was the SAME warehouse where the Govt.  hid everything that folks were not to know about.  Recently, I decided to try to use this warehouse in a role-playing game, for fun.  I've been trying to figure out things that should be in some of the boxes.  I'...
