vgetty play problem.

• Messages sorted by:[ date ][ thread ][ subject ][ author ]

Hi, I'm trying to get a simple vgetty script working.

I'm basically synthesising speech using festival and sending it to the
modem. My problem seems to be that if the speech file is longish, an error
occurs.

My minimal script that fails is (with events enables):

synth_and_play_text "$short_message"
synth_and_play_text "$longer_message"

where long_lessage is about 10 words in length.
and the synth_and_play_text function synthesises to .wav converts to .rmd
issues 'send "PLAY $FILE"' and waits for  PLAYING and READY responces.

The fist message plays ok, but the second message doesn't

The script gets the `PLAYING' responce but not the `READY' responce for
the second message.

the vgetty log has the following for the second message:

10/25 15:01:10 yS0   shell(1): PLAY /tmp/vgetty_spt28632
10/25 15:01:10 yS0   vgetty(1): PLAYING

10/25 15:01:21 yS0   vgetty(1): READY

Modem reports itself as a:

1.0USR9180\\Modem\PNPC107\U.S. Robotics 56K Voice EXT

mgetty is patched with mgetty-1.1.21-to-16091999.patch

I don't think I've changed any defaults.

I'm assuming the modem returning VCOM at "10/25 15:01:10" instead of OK is
the problem, but I don't know what this means or how to fix it.

Any help much appreciated.
