Now that I've got two CP/M-80 machines up and running, I've had a chance to play around with a thought: sending files between CP/M machines with no terminal software using PIP. Both my Kaypro II and the Apple IIe with Microsoft SoftCard apparently have their IOBYTE set so that RDR: and PUN: are attached to the serial controllers. PIP PUN:=A:TEST.TXT with a null modem cable between the two results in a textfile showing up on the IIe if I've got terminal software running.
My question is, how does one set the baud rate on a machine if you don't have terminal software? It's not a problem with the Kaypro II since the CP/M distribution comes with BAUD.COM to set the baudrate for TERM.COM. The distribution for the Z80 SoftCard has no such utility though.
I know I can write a short Assembly program to talk to the serial chip and set baud rate, but I was wondering if there was a default set for CP/M. Eventually, I want to use this method to send files to/from my NEC APC so that I can get a proper terminal program assembled.
