RS232 serial gurus

[u2slow]

I have a host system with a DB25 male serial port. The serial printer has a DB25 female port. It takes a standard DB25 female/male serial printer cable.

Supposing I interrupt this simple setup with two DB9 terminal-server devices to create a serial tunnel over the Internet....

Now I need 2 different DB25/DB9 cables. Is it appropriate to use regular modem cables, with the addition of a gender-changer on the host side? Or does this combination of cables and changers cross up the signals and turn it to garbage?

No one?

I must be starting to get a handle on this stuff. I managed to get WinXP to recognize a modem across back-to-back port servers.

PC serial port -----> 1st port server -----> ethernet hub -----> 2nd port server -----> USR 28.8 modem.

A printer can't be much harder - I hope.
