Hi. I've noticed that you cannot use 'xmodem' or 'sx' or other XMODEM-type
file transfers if you are logging a transcript of your session with the
utility 'script'. 'script' uses pty's...when attempting XMODEM transfers,
all one gets is errors til XMODEM or the communication program aborts.
Given that I have XMODEM source code, is there a fix that will get it to
work while a pty is your controling terminal? Has anyone else found a fix?
Thanx.

My PC XT was connected to our Sun 3/110 through a serial port. I was able to transfer files back and forth at 9600 baud using the YMODEM batch protocol (PROCOMM on the PC and Steve Grandi's YMODEM program on the Sun); I had no problems. We recently bought a CMC TranServer terminal server which is connected to the Sun via Ethernet and our PC's are connected to the terminal server at 9600 baud (8 bits, no parity). We use TELNET on the terminal server to open a session on the Sun; the Sun has a PTY on its side. Everything works fine (VI, MicroEMACS, etc.) except for file transfers between the machines. Transferring files from the Sun to the PC using YMODEM batch works great, but transferring files from the PC to the Sun does not. File names are exchanged, but the Sun's YMODEM program keeps timing out "while reading sectors 1-8" (from the debug file) and eventually it aborts the transfer. Our UNIX-based KERMIT program has the same problem: Sun->PC transfers work fine, but PC->Sun transfers keep timing out. The transfer continues, but at a reduced data rate (a few hundred bytes per minute!). It seems like the problem has to do with PTY's - what should be done? Thanks! Alex Measday Integral Systems, Inc.
