Hi, I've been trying to set up a ppp server on my FreeBSD-2.2.2 machine and thus far, I can get user ppp and pppd working fine on my internal modem at any speed. My problem is when I try to run user ppp and pppd on external modems. I have an external modem connected to a standard serial port on my computer (its on my controller card) and another external modem connected to a Digiboard PC/8e, 8 port serial card. The problem is that I cannot log in (via getty/login, getty/login/user ppp or PAP/pppd) at speeds higher than 9600 baud. 9600 baud and lower is no problem from a connection standpoint but I wouldn't want to be dialing in for anything more than email without attachments at that point. Interestingly though is the fact that I can set up terminal software on both ends, set the modems for speeds higher than 9600 baud, they connect, and I can type back and forth. When I say I cannot log in at speeds higher than 9600 baud, I mean, I don't get the login prompt (in the case of getty) and authentication never takes place in the case of pppd. On the client side, logs have shown (in the case of pppd) that LCP configuration request were sent but the server side ignores them. It seems a bit coincidental that 9600 appears to be the "cut off" speed - my experience has been that at speeds above 9600, hardware handshaking is required. Is is possible that both the getty and pppd or perhaps sio is having a problem with hardware handshaking? In my /etc/ppp/options file, the first line is crtscts (hardware handshaking) and this is also how the serial devices are configured (and locked, I made no changes to the rc.serial file with the exception of specifying which devices are where at the bottom of the file). Thanx, David surly@computer.net
