- (Here is a copy of a letter I mailed to Tom. There is a specific
- question for the net at the bottom. Bob)
-
- Hi Tom;
-
- I'm trying to debug the use of a loaner modem - a Viva 9642e - and I have
- some suggestions:
-
- 1 - debug: modem
-
- Please document the meaning of those colons "::::::" that fill the
- screen. They are actually obstructive because all the read information
- scrolls off before it can be read.
-
- I suspect they are somekind of tic marks, representing waits. If so,
- replace them with something that will not clear the screen.
-
- *MODEM: peek = 13 CR
- *MODEM: peek = 10 LF
- *MODEM: peek = 79 "O"
- *MODEM: responding OK|
-
- Now what does that mean? Can I assume that you report each byte
- returned from the modem post until you figure out what it is?
-
- *MODEM flushed: 12 FF
- *MODEM flushed: 10 LF
- *MODEM flushed: 13 CR
- *MODEM flushed: 10 LF
- *MODEM flushed: 78 "N"
- *MODEM flushed: 79 "O"
- *MODEM flushed: 32 SP
- *MODEM flushed: 67 "C"
- *MODEM flushed: 65 "A"
- *MODEM flushed: 82 "R"
- *MODEM flushed: 82 "R"
- *MODEM flushed: 73 "I"
- *MODEM flushed: 69 "E"
- *MODEM flushed: 82 "R"
-
- What is the difference between flushed and peek?
-
- Since I am running on a DOS system, scroll off is a real problem.
- Please change it to something like:
-
- *MODEM flushed: 12, 10, 13, 10, 78, ...
-
- to keep scrolling to a minimum.
-
- 2 - modem scripting
-
- Because of the inherent slow response of this modem to initialization
- commands, the only way that I can succesfully initialize it on a
- consistant basis is by waiting for the OK response. This can easily
- be done in the "dialers" file.
-
- How about providing the same functionality for initialization,
- autoanswer, etc?
-
- 3 - modem status checking
-
- Most modems today, in addition to added status messages that choke
- Waffle {CARRIER 9600}, have many status registers that are helpful
- in debugging connections.
-
- How about an option to allow specification of a status check, with
- the results echoed back to the console?
-
- initialized : AT Z0 | AT&V | <-- reset modem, print register contents
-
- ---------------- for those of you monitoring on the net ------------------
-
- One of the problems with this modem relates to dealing with plain, vanilla,
- 2400 baud modems. If you initialize the modem at 2400 baud, it will answer
- the phone and connect to a 2400 baud modem. If you initialize at greater
- than 2400 baud, it chokes...
-
- Any clues? (A Viva 9642e)
