Problema assombroso com modem
Oi pessoal,
Ontem começei a ter desconexões aleatórias do modem (US Robotics
Sportster
56K ISA, voice/fax), analisando nos logs verifiquei que o PPPD estava
recebendo
um sinal SIGHUP. O log segue em anexo.
O sinal enviado é muito estranho, e pensei até ser um bug ou
corrompimento
no daemon ppp do kernel, mesmo recompilando uma versão anterior do
kernel
e instalando, o problema persistiu.
Testei o modem em outra máquina Linux e Windows, funcionando
perfeitamente. A configuração é feita manualmente funcionando na
I/O 0x0x2F8 IRQ 3, sem conflitos com nenhum dispositivo e a porta
serial desabilitada na placa controladora on-board.
Gostaria de sugestões para resolver este estranho problema, caso alguém
já tenha passado por isso. Eu já tive um probleme semelhante com um
outro modem (o outro era problema na placa) e foi resolvido com sua
substituição.
