Problem with Modem::Vgetty

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

Hello!

Attempting to write an answering machine in Perl, I run into the following 
problem:

calls to IO::Handle::print (and possibly read) seems to corrupt something... I 
really wonder what can cause messages like these:

Filehandle Symbol::GEN2 never opened at /usr/local/lib/perl5/5.00502/i386-freebsd/IO/Handle.pm line 379, <GEN0> chunk 1.
Filehandle Symbol::GEN2 never opened at /usr/local/lib/perl5/5.00502/i386-freebsd/IO/Handle.pm line 379, <GEN0> chunk 2.

Filehandle Symbol::GEN2 never opened at /usr/local/lib/perl5/5.00502/i386-freebsd/IO/Handle.pm line 379, <GEN0> chunk 4.

and, what's the worst of all, these messages comes to script running from 
vgetty as modem responces. clobbering any work.
