 Some other common speeds are 9600, 57600, 38400, 19200.  For the Beagle Bone black, I always use 115200.  These speeds are in baud.

+This section below is from some revisions I wrote for Jason's beaglebone stripping tutorial ...
+==Clean Up Post-Install==
+  apt-get install screen deborphan ntp
+the new version has an ntp server
+be sure to fix /etc/network/interfaces before removing connman - uncomment the lines for DHCP for eth0, remove extraneous lines and the manual entry that comes stock with bbb ... then connect to the beaglebone with ssh and screen ...
+  ssh -t root@<x.x.x.x> screen -DRO
+  for i in udhcpd chromium-codecs-ffmpeg-extra connman lximage-qt lxmenu-data pcmanfm-qt qupzilla xserver-xorg-core "light*" chromium-browser nodejs "lxqt*" xserver-common "apache2*" bluez "xfonts*" "x11-*" "x11proto-*" build-essential alsa-utils; do apt-get -y purge $i; done
+After this command, the ssh session hung, and we could only access with screen at a different speed of 9600 ... but, as long as you took care of /etc/network/interfaces above, then a reboot (worst case) or waiting should bring it back up.
+  apt-get --purge autoremove
+  apt-get --purge remove `deborphan` OR [apt-get purge `deborphan`] OR [apt-get purge $(deborphan)]
+run deborphan a few times untill all is removed
+  apt update
+  apt dist-upgrade
+  apt clean
+edit /etc/issue.net to remove the goofy ssh splash
+  cd /var/log && rm lastlog && ln -s /dev/null lastlog
+  cd /etc/cron.daily && mv man-db man-db.disabled [if it exists]
+to find latest writes to disk: find / -mount -newermt 14:44:00 [to see what logs are post-updates, i.e., for limiting writes to eMMC]
+Verify /etc/fstab configuration, include noatime like this example
+  FROM FSTAB:
+  UUID=57e4a3f6-7951-40ae-ad25-b445959e1c30  /  ext4  noatime,errors=remount-ro  0  1
+  debugfs  /sys/kernel/debug  debugfs  defaults  0  0
+#if we use an external sdcard, we are less concerned with re-writes, so enable the logs on the sdcard (create directories for each location below, mountpoints, etc.)
