Default ttyS1 buffer overflow for serial console in Ubuntu 8.04.1 server

I have setup a serial console on ttyS1 according to http://www.howtoforge.com/setting_up_a_serial_console. The problem is that I'm losing lots of characters on the serial console when the system boots. I assume this is due to a buffer overflow on the serial port. Some lines of boot text appear correctly, but there is a little time between them. Fast lines, especially those with a lot of spaces in them, drop many characters.

I'm using hyperterminal on a PC as a client. I have the same results when using two different PC's as a client, so the problem must be in Ubuntu 8.04.1 server.

How do I fix this ?

I'm using 115200n8. It is only a two-wire (+ ground) serial interface so I can't use hardware handshaking.

Thank you.
