I'm sorry Igor, but english is not my first language, so what do you mean by "accounted"? If you are using modems in a leased line config, yes they act as a null modem between you and your provider. But, do you want to use modems instead of a null modem? or do you want to use a null modem instead of modems? What exactly is the problem you are having? -- Pablo Quintana NetSys Dedicated Internet Services San Pedro Sula, Honduras, Central America e-mail: quintana@netsys.hn Voice: +(504) 566-1055 Fax: +(504) 566-3183 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
