We have bought a dozen Fastrack Supreme modems. We want to poll outlying slave equipment from a central master Linux box.
We are having difficulty dialing and logging onto the outlying equipment. We’ve tried (1) using a terminal program (minicom) to talk to the modem – “AT”, “ATDTnnnn”, etc, work just fine. And (2) using pppd to dial a landline works just fine, but authentication to an outlying box to a second Fastrack Supreme just doesn’t work.
So far, we’ve tried variations on this: this is /etc/ppp/peers/wavecom_00:
/dev/ttyS0 9600 # The following are from Fastrack/GPRS UserGuide.pdf: nodetach debug kdebug 7 crtscts name F075PPP connect "/usr/sbin/chat -vs ECHO OFF AT\r OK ATE0V1\r OK ATDT0458783786 CONNECT" novj nomagic asyncmap 0 defaultroute usepeerdns
The command then used is
pppd file /etc/ppp/peers/wavecom_00
The /var/log/messages file only shows:
Oct 19 16:35:11 lw-scada-ppp1 pppd: pppd 2.4.4 started by ppp, uid 0 Oct 19 16:35:12 lw-scada-ppp1 chat: expect (AT^M) Oct 19 16:35:57 lw-scada-ppp1 chat: alarm Oct 19 16:35:57 lw-scada-ppp1 chat: Failed Oct 19 16:35:57 lw-scada-ppp1 pppd: Connect script failed Oct 19 16:35:58 lw-scada-ppp1 pppd: Exit.
Any suggestions, either actual set-up, or links to useful documentation, would be warmly welcomed.
Thanks in advance.
