Hello,
Two parter:
1. Using U.S. Robotics external modems for autodialing (followed by touchtone
commands for accessing voicemail, etc.). After a few times working well, it
stops. LED on the modem flash quickly, but no dial tone or anything.
If I turn the modem off then on again, it's fine.
Is there something I'm not doing to clear or reset? Simple code like:
OPEN COMMS USING Port%,2400,0,1,8,1,0,1,1,0,0,"",""
COMMS ? "atdt" + NumPrefix$ + TelSelected$ + CHR$ (13)
REQUEST "Select phone line when ringing.",NumPrefix$ +
TelSelected$,100
COMMS ? "ath0" + CHR$ (13)
CLOSE COMMS
I've tried adding things like ATZ , but can't find anything that helps.
2. I seem to remember a limit on number of characters in a string that you can
send to a modem. Anybody know if that's true and what that limit is?
Is there a way to build the program in stages or something so that it can
continue with many commands/instructions?
Thank you for any guidance.
Best regards,
John |

This is a very simple comms routine and i presume you are just sending lines of
ascii code from one modem to another.
1) Try COMMS ? "+++" followed by COMMS ? "ATH0" to force
the line to hang up eg:.
OPEN COMMS USING Port%,2400,0,1,8,1,0,1,1,0,0,"",""
COMMS ? "atdt" + NumPrefix$ + TelSelected$ + CHR$ (13)
REQUEST "Select phone line when ringing.",NumPrefix$ +
TelSelected$,100
COMMS ? "+++"
COMMS ? "ath0"
CLOSE COMMS
2) There is no limit that i know off but information is sent in packets. Make
sure you collect each packet of text sent and add it together eg:
WHILE com$ <> terminate$
COMMS GET com$
allcom$ = allcom$ + com$
WEND
This is the simplest way of receiving unlimited data from one modem to another.
It waits for a specific character to terminate the send.
WHILE LEN (com$) > 0
COMMS INPUT com$
allcom$ = allcom$ + com$
WEND
This will read up to 4000 characters at a time in the comms buffer and add them
to allcom$ on the fly.
If you need to send more than 4000 characters, you should probably be sending
files instead of characters.

Thanks again, Axel! That "+++" seems to have cleared it up.
The only time I have to reset (power down/up) the modem is if I abort the
dialing process before it's complete... probably before it gets to
"+++". Do
you happen to know how I can catch the incomplete process and send
"+++"?
